Omega

The Omega keyword creates a lasting effect that states, “The active player cannot play, use, or discard any more cards for the remainder of the current step of the turn sequence except through the resolution of pending abilities and effects.”

When playing a card with Omega, this lasting effect is created as the card enters play (for artifacts, creatures, and upgrades), or immediately after the card is revealed (for action cards). If a card would gain omega as it enters play, the lasting effect is created as the card being played enters play.

Once the pending abilities and effects have completed their resolution, play continues to the next step of the turn sequence. If the card with Omega leaves play during the resolution of the abilities and effects, the current step of the turn sequence still ends when resolution is complete.

• My opponent has Autocannon (COTA 019) in play and I play Duskwitch (AOA 320). Can I resolve the effects in such a way that Duskwitch’s Omega keyword does not resolve??
  No. Omega’s lasting effect is established as Duskwitch enters play, meaning the active player cannot play, use, or discard any more cards for the remainder of the step except through the resolution of pending abilities and effects.

  The resolution of Autocannon’s ability in the “after a card is played” window will result in Duskwitch being destroyed, but the lasting effect from Omega is already established and the step will still end once pending abilities and effects complete their resolution.

• My opponent has Chronophage (DT 017) in play, with 2 damage on it. I play a creature that has a damage bonus icon on it, and apply the damage to my opponent’s Chronophage. Did my creature still gain the Omega keyword, meaning I end the step, or was Chronophage moved out of play before its ability could resolve on my creature, meaning I can continue to play and/or use cards in the current step?
  The creature that was played gained the Omega keyword as it entered play, so the Omega keyword will resolve as if it were on the card when the card was played.

• My opponent plays Shadow of Dis (AOA 103). I have Duskwitch (AOA 320) in my hand. May I play Duskwitch, then play other cards afterwards?
  No. Omega’s lasting effect is established as Duskwitch enters play, meaning the active player cannot play, use, or discard any more cards for the remainder of the step except through the resolution of pending abilities and effects. Even though Duskwitch’s text box is blank once it is in play, the effect from Omega has already been created.
