The Sorcery Turn Structure: Start, Main, End — and What You Can Do When

Three phases, one draw, and a permanent choice between two decks. The Sorcery turn isn't an MTG turn — here's how it actually flows.

rules beginner reference

If you came from Magic, the Sorcery turn looks deceptively familiar. Untap, get mana, draw, do things, end. Three phases instead of MTG's seven; no separate combat step; no priority back-and-forth. Easy.

The trap is what happens during the draw. Every turn you draw exactly one card, and you choose whether it comes from your Atlas or your Spellbook. This single mechanic — one card, two decks, a permanent decision every turn — is the most non-obvious rule in the game for MTG transplants, and it's the place where the most "I should have won that game" losses live. Most new players default to Spellbook for the first five turns. Don't.

This article walks through the three phases of a Sorcery turn — what triggers when, what you can do, and what you can't — with the draw choice as the spine.

The three phases at a glance

A Sorcery turn has exactly three phases, in order:

  1. Start Phase — untap, mana, triggered abilities, draw
  2. Main Phase — everything you actually do
  3. End Phase — cleanup and end-of-turn triggers

That's it. No upkeep step, no draw step separate from start of turn, no combat phase, no end step distinct from cleanup. The Sorcery turn is intentionally consolidated — three phases, four sub-steps each on the bookend phases, free-form action in the middle.

If you're used to MTG's seven steps (untap → upkeep → draw → main1 → combat → main2 → end), the mental adjustment is that combat is not a separate phase. Attacks are activated abilities, executed during your Main Phase, in any order alongside spells and movement.

Start Phase — what triggers when

The rulebook lists four steps, in order, for the Start Phase:

"Step 1. All of your cards that are tapped now untap. Step 2. All of your sites now provide their mana for this turn. Step 3. Trigger abilities that happen at the start of the turn. Step 4. Finally, draw a card from either your spellbook or atlas."

The ordering matters, and the 2024 rulebook explicitly reordered it from earlier versions. Untap happens before mana refill, which happens before triggered abilities, which happens before you draw. If a triggered ability checks the state of your sites, it sees them already-untapped and already-providing-mana. If a triggered ability cares about whether you have a hand, it fires before the draw — so you may end up with an empty-hand trigger that you can't immediately respond to.

One catch on Step 4. First player skips their draw on turn 1. The rulebook is explicit: "If you are the first player to take a turn in the game, skip Step 4 of the Start Phase." Everyone else, every other turn, draws exactly one card. This isn't about going-first advantage — it's the game's way of normalizing the tempo gap.

The choice that defines Sorcery — one card, two decks

The single most important rule on Step 4: you choose which deck to draw from.

Every Sorcery player runs two decks at the same table:

  • Spellbook — minions, magic, auras, artifacts. The 60-card-minimum deck (as of the December 2025 rulebook update standardizing Constructed at 60).
  • Atlas — sites. The 30-card-minimum deck of landscape-oriented Site cards that provide mana and threshold.

Every turn at Step 4, you decide: pull from Spellbook, or pull from Atlas. Not both. Not "draw a card and a site." One card from one deck.

This rule eliminates mana screw and mana flood by construction. There's no shuffle-luck on lands. If you need a site, you draw a site. If you need a spell, you draw a spell. The cost is that you have to decide which, and you have to decide it every single turn for the entire game.

The default new-player mistake. People come from Magic, where you draw a card unconditionally and lands are part of the same deck, and they default to drawing spells. They have a hand full of spells already — why draw more sites? After five turns they're sitting on 2-3 sites total, can't cast their threshold-locked threats, and lose to an opponent who built out to 5-6 sites in the same time.

The right default, especially through the first 5-6 turns: draw from the Atlas until your mana curve is met and your threshold requirements for the spells in your hand are unlocked. The Atlas pull is also a site-played-onto-the-board action if you choose — the Avatar's tap can play a site from hand. Drawing from Atlas builds your board state directly; drawing from Spellbook only adds resources you can't deploy until your mana and threshold are in place.

Heuristic: what's blocking the spell I want to cast?

  • If the answer is "I don't have enough mana" or "I don't have the right threshold" → draw from Atlas.
  • If the answer is "I have the resources, I just need the threat" → draw from Spellbook.
  • If the curve is already met for the next two turns → draw from Spellbook.
  • If you're in topdeck mode for a finisher or an answer → draw from Spellbook.

The choice is more important than mulligan, more important than mana sequencing, and gets easier with practice. The Sorcery games you'll look back on and curse are the ones where you defaulted Spellbook five turns in a row and lost to mana-color problems you couldn't fix.

Main Phase — what you can do

The Main Phase is where the game happens. From the rulebook, on what you can do during this phase:

"You may have your units do these as many times as you have resources to do so, and in any order you like. For example, you might move a minion, then cast a spell with your Avatar, and then move another minion."

Everything in Main Phase is one of two things:

  • Cast a spell — your spellcasters (Avatar and any minions with spellcaster status) cast spells from your hand using mana and threshold.
  • Activate an ability — any minion or Avatar uses one of its abilities, basic or unique.

What "activate an ability" includes is broader than it sounds. The Move and Attack behavior is itself an activated ability. Playing a Site from the Atlas is the Avatar's activated ability. Picking up and dropping artifacts use the Pick Up / Drop basic abilities. Casting a spell is the only "spell-cast" action; everything else is ability activation.

There's no instant-speed equivalent. Once the Main Phase begins, you sequence your actions in any order you want. Your opponent doesn't get a priority pass between your actions. You play your turn; they wait; they get their turn.

What you can do during opponent's Main Phase: only the Defend and Intercept triggered abilities — both of which are reactive responses to your opponent attacking your minions or Avatar, not voluntary card plays. Sorcery has no spell-casting on the opponent's turn. None.

If you played MTG and relied on Counterspell as an interactive layer, that interaction model doesn't exist here. The game's interaction happens through Defend, Intercept, and the fact that your opponent's Main Phase is also your next Main Phase — you respond by surviving and replying.

Site placement and movement, inside the Main Phase

Two specific Main Phase actions deserve a closer look because they don't have clean MTG analogs:

Site placement (and Atlas top-deck). Every Avatar has a baseline activated ability the rulebook prints as "Tap → Play or draw a site." The Avatar's tap does one of two things: play a Site from your hand onto the board, or draw a site directly from the top of your Atlas. This is separate from the Step 4 Start Phase draw — meaning a player who draws from Atlas at Step 4 and uses the Avatar tap to draw another Site in Main Phase can effectively pull two sites in a single turn. Sites must be placed on a Void (empty) square adjacent to a Site you already control. The chain extends from your Avatar outward.

Movement. Most minions have the Move basic ability — tap to step to an adjacent square. The grid is 5×4, twenty squares total, and movement is one step per activation. Flying minions ignore some movement restrictions; burrowing and submerging minions ignore others. The full mechanic gets its own article — see the prerequisite Threshold and Sites for how Sites set up the board you're moving on.

Combat — attacking and being attacked — also lives entirely inside Main Phase as an activated ability. For the combat math itself (power vs. defense, ranged vs. melee, Defend and Intercept), see How Combat Works in Sorcery.

End Phase — what resolves

The End Phase mirrors the Start Phase structurally:

"Step 1. Trigger abilities that happen at the end of the turn. Step 2. Players remove all damage from their minions in the realm. Step 3. Effects that last for your turn now end. Step 4. Your turn ends."

Four steps, in order. End-of-turn triggers go first — those "at the end of turn" abilities resolve here. Then damage clears from minions. Then "for your turn" durational effects expire. Then the turn ends and your opponent's Start Phase begins.

One critical asymmetry. Damage clears from minions. Damage on your Avatar does not clear. The rulebook is explicit:

"Avatars do not heal automatically at the end of the turn in the same way as damage is removed from minions, however they can heal using spells and other card effects."

This is huge. An Avatar at 5 life stays at 5 life at end of turn. A minion at 1 power that took 2 damage but didn't die during combat? It clears the damage and resets to full power at end of turn. The Avatar is a persistent, tracked life total; minions are turn-by-turn objects.

It also means the Death's Door rule — the one that lets an Avatar at 0 life survive the rest of the current turn — is not an end-of-turn cleanup. It's a state. Once at Death's Door, you stay at 0 until you take a Death Blow. End Phase doesn't restore you.

A worked turn: Avatar of Fire, turn 3

Let's walk through a real turn end to end. You're playing Avatar of Fire, mono-Fire. It's turn 3. You go first. Board state going in: you have two Fire sites in play, mana pool empty, opponent has two sites and a 1/1 Beggar on the board.

Start Phase.

  • Step 1: Your sites and Avatar untap.
  • Step 2: Both your Fire sites provide 1 mana each. You now have 2 mana available for the turn.
  • Step 3: Trigger abilities resolve. None on the board.
  • Step 4: Draw choice. Your hand has Crackling Bolt (1-cost burn) and a Fire site you can't cast (no mana to spare yet). You want a third site for mana ramp into Avatar of Fire's burn ability later. Draw from Atlas. You pull a Fire site.

Main Phase.

  • Tap your Avatar to play the Fire site you just drew, placed adjacent to your existing chain. Board: 3 Fire sites, threshold 3 Fire. The Avatar's site-placement ability is a tap, not a mana cost — you still have 2 mana to spend.
  • You could cast Crackling Bolt for 1 to deal 2 damage to the Beggar — that kills it.
  • You could hold Crackling Bolt for next turn when you've drawn another threat and want to push damage to the Avatar.
  • Decision: cast Crackling Bolt on the Beggar. Spend 1 mana. Beggar dies. 1 mana unspent at end of Main Phase.

End Phase.

  • Step 1: No end-of-turn triggers.
  • Step 2: No minions on your side, no damage to clear.
  • Step 3: No "for your turn" effects to expire.
  • Step 4: Turn ends. Pass to opponent.

You exit turn 3 with three Fire sites on board, an empty hand, and the Beggar dead. You traded a card for a card; you ramped one site. Both are good outcomes.

The decision that actually mattered was Step 4 of Start Phase: draw a site or draw a spell? Drawing a spell instead of the site would have left you at 2 mana with no path to ramp further, no way to power Avatar of Fire's burn finisher next turn. The Atlas pull was correct because the spell in hand wasn't the bottleneck — the mana was.

That's the entire mental model the article is built around: every turn, ask what's blocking the play you actually want to make, and pull from the deck that unblocks it.

What's changed recently — and what hasn't

The rulebook is a live document. Two recent updates matter for turn structure:

The 2024 rulebook reordered Start Phase steps. From an earlier version, the publisher's update notes say: "The steps of the Start Phase have been reordered. Your cards will now untap and sites will provide mana before start of turn triggers occur." So untap → mana → triggered abilities → draw is the current order, and earlier copies of the rulebook may show a different sequence. Always use the latest rulebook PDF.

The December 2025 update did not change turn structure. The update standardized Spellbook size at 60 cards for Constructed, added Ward / Collection / "Can't Be Modified" as formal glossary entries, and clarified Stealth, Pick Up, and Transform. None of those changes touch the phase ordering or the draw choice. The turn structure as documented above is current as of mid-2026.

There is no separate "July 2025 combat update" in the published news archive — that timing reference circulated informally, but the rulebook revisions that affect turn structure trace to the 2024 publication and the December 2025 glossary additions only.

Common MTG-brain mistakes

Three patterns I see Magic players hit:

Treating the draw as automatic-from-Spellbook. Magic conditions you to draw spells. Sorcery rewards you for drawing sites — at least until your mana base and threshold curve are filled in. Default to Atlas through the early game.

Looking for instant-speed plays during the opponent's turn. There aren't any. Defend and Intercept are the only opponent-turn actions you can take, and both fire automatically when your minions or Avatar are attacked. There is no equivalent of "untap, draw, response?" — you wait, your opponent finishes, then it's your turn.

Expecting end-of-turn to restore Avatar life. It doesn't. Avatar damage persists; only minions reset at end of turn. The asymmetry is in the rulebook in plain text, and it's the source of more "wait, why am I dead?" moments than any other rule for Magic transplants.
