Start of Turn step (formerly known as the Untap Step) is the first step of a turn.


Any of your creatures in the battle zone as well as the cards in your mana zone are untapped.

This will allow you to re-use mana cards and attack with creatures again.


  • If a creature with a Silent Skill ability exists in the battle zone in a tapped state at the start of your turn, they may keep themselves tapped by their ability at the start of the turn.
  • If Belfegius, Emperor of Death is in the battle zone, it is optional to untap creatures. If a player decides to untap his creatures save for Belfegius itself, it will be destroyed instantly by Belfegius.
  • If Warped Lunatron is in the battle zone, creature's wont untap in this step.
  • Once they are affected by Freeze, they won't untap in the next start of turn step.
  • After the March 25, 2017 Rules revision, the order of steps was changed. The "start of turn" triggers are now performed after the cards in the battle zone and your mana zone are untapped.
  • When sending a creature that taps the opponent's creatures via Shouten, Stellar Guidance's last effect, the creatures will stay tapped since they untap before Shouten sends out the creature.

  • 501. Start of Turn Step
    • 501.1 The active player determines which cards they control will untap. Then they untap them all simultaneously. This is a turn-based action. Normally, all of a player’s cards untap, but effects can keep one or more of a player’s cards from untapping.
      • 501.1a The active player may replace the untapping of his creatures with the "Silent skill" ability. However, the effect of the "Silent skill" itself is independent of the invocation condition. The activation of "Silent skill" produces an effect which is resolveded after the other cards untap.
    • 501.2. Any abilities that trigger "at the start of turn" trigger. The induced effect is a turn We declare solutions to be resolved from the layer and process them in order.
      • 501.2a If a card with an ability that triggers "at the start of turn" is moved to a zone where it works from after the time of triggering, that card's ability will not trigger until the next start of turn step.

  • Cards such as Vacuum Crawler or Intense World! Shachihoko Kaiser resolve their abilities directly after this step.
  • This step is followed by the Draw Step.
  • The process of untapping a card is a forced rule.
  • Creatures that weren't in the battle zone at the start of the start of turn step won't be untapped during your turn. For example, if you put a Miss Mei, Forest of Sleeping into the battle zone during your Main Step, you will be unable to untap it until your next turn.
