Setup
Bring a Main Deck of 40–60 cards, an Extra Deck of up to 15 (Fusion, Synchro, Xyz, and Link Monsters), and an optional Side Deck of up to 15.
Both players shuffle and draw 5 cards (some formats use 6). Determine who goes first by rock-paper-scissors, dice, or coin flip.
Both players start at 8000 Life Points.
The Field Zone holds a Field Spell. There are separate zones for Monster, Spell/Trap, Pendulum, Extra Monster, and Graveyard.
How to play
- 1
Each turn follows a fixed structure: Draw → Standby → Main 1 → Battle → Main 2 → End.
- 2
During Main Phase 1, you can Normal Summon or Set one monster per turn from your hand (unless a card lets you do more), and freely play Spells or Set Traps.
- 3
Special Summons don't count against your one Normal Summon — most modern decks Special Summon many times per turn.
- 4
Extra Deck monsters are Special Summoned through Fusion, Synchro, Xyz, Link, or Pendulum mechanics, each with their own conditions.
- 5
The turn player cannot attack during the Battle Phase of turn 1.
- 6
Reduce your opponent to 0 LP, deck them out, or fulfill a card's alternate win condition (Exodia, Final Countdown, etc.) to win.
Anatomy of a turn
- 1
Draw
Draw one card from the top of your deck. If you can't, you lose. Skipped on turn 1 for the first player only in some variants — in the OCG/TCG both players draw on turn 1, but the first player cannot attack.
- 2
Standby
Resolve any maintenance costs or Standby Phase triggers.
- 3
Main Phase 1
Normal Summon/Set (once), Special Summon, play Spells, Set Traps, change monster positions, activate ignition effects.
- 4
Battle Phase
Start step → Battle step (declare attackers) → Damage step → End step. Only the turn player can attack.
- 5
Main Phase 2
A second window for summons and card plays. Useful after seeing combat results.
- 6
End Phase
Discard down to 6 cards. End-phase effects and hand traps resolve.
Rules to know
Chains and Spell Speed
Effects have Spell Speed 1 (normal), 2 (Quick / most Traps), or 3 (Counter Traps). Higher-speed effects can respond to lower ones. Chains resolve last-in, first-out.
Summoning rules
Level 5–6 monsters need one Tribute; Level 7+ need two. Special Summons bypass this. Extra Deck monsters have specific summon requirements printed on the card.
Monster positions
Attack Position or Defense Position (face-up or face-down). A Defense Position monster attacked by a stronger monster is destroyed but its controller takes no damage.
Card zones
5 Monster Zones, 5 Spell/Trap Zones, 2 Extra Monster Zones (shared), 1 Field Zone. Link Monsters can open more Extra Deck plays by pointing to zones.
Set vs Activate
Traps must be Set face-down first; they can only be activated starting from the next turn. Quick-Play Spells set the same way, and can be activated on your opponent's turn too.
Life Points as a resource
Some cards cost LP to activate. Going low on LP can enable powerful effects — but leaves you one attack from losing.
Win conditions
Reduce your opponent's Life Points to 0.
Your opponent cannot draw a card at the start of their Draw Phase.
Alternate win conditions printed on specific cards (Exodia the Forbidden One, Final Countdown, Vennominaga, etc.).
Your opponent surrenders or receives a Match Loss for a rules violation.
Play smarter, faster
Modern Yu-Gi-Oh! is combo-heavy. Learn one deck's full turn 1 line before branching out.
Hand traps (Ash Blossom, Effect Veiler, Nibiru) are how you interact on your opponent's turn — most decks run 10+ of them.
Read the fine print on Special Summon effects. 'Once per turn' vs 'Hard Once per turn (this effect can only be used once per turn)' is a big difference.
Don't Normal Summon reflexively on turn 1 if your Special Summon combos don't need it — you may want it later.
