Beginning of a phase

How to play instructions

• Untap step
  You untap all your tapped permanents. On the first turn of the game, you don’t have any permanents, so you just skip this step. No one can cast spells or activate abilities during this step.

• Upkeep step
  Players can cast instants and activate abilities. This part of the turn is mentioned on a number of cards. If something is supposed to happen just once per turn, right at the beginning, an ability will trigger "at the beginning of your upkeep."

• Draw step
  You must draw a card from your library (even if you don’t want to). The player who goes first in a two-player game skips the draw step on their first turn to make up for the advantage of going first. Players can then cast instants and activate abilities.

first main phase

• You can cast any number of sorceries, instants, creatures, artifacts, enchantments, and planeswalkers, and you can activate abilities. You can play a land during this phase, but remember that you can play only one land during your turn. Your opponent can cast instants and activate abilities.

combat phase

• Beginning of combat step
  Players can cast instants and activate abilities.

• Declare attackers step
  You decide which, if any, of your untapped creatures will attack, and which player or planeswalker they will attack. This taps the attacking creatures. Players can then cast instants and activate abilities.

• Declare blockers step
  Your opponent decides which, if any, of their untapped creatures will block your attacking creatures. If multiple creatures block a single attacker, you order the blockers to show which will be first to receive damage, which will be second, and so on. Players can then cast instants and activate abilities.

• Combat damage step
  Each attacking or blocking creature that’s still on the battlefield assigns its combat damage to the defending player (if it’s attacking that player and wasn’t blocked), to a planeswalker (if it’s attacking that planeswalker and wasn’t blocked), to the creature or creatures blocking it, or to the creature it’s blocking. If an attacking creature is blocked by multiple creatures, you divide its combat damage among them by assigning at least enough damage to the first blocking creature to destroy it, then by assigning damage to the second one, and so on. Once players decide how the creatures they control will deal their combat damage, the damage is all dealt at the same time. Players can then cast instants and activate abilities.

• End of combat step
  Players can cast instants and activate abilities.

second main phase

• Your second main phase is just like your first main phase. You can cast any type of spell and activate abilities, but your opponent can only cast instants and activate abilities. You can play a land during this phase if you didn’t play one during your first main phase.

ending a phase

• End step
  Abilities that trigger “at the beginning of your end step” go on the stack. Players can cast instants and activate abilities.

• Cleanup step
  If you have more than seven cards in your hand, choose and discard cards until you have only seven. Next, all damage on creatures is removed and all “until end of turn” effects end. No one can cast instants or activate abilities unless an ability triggers during this step.
