5 rulings from Wizards of the Coast
- 2 February 2024An ability that triggers “whenever you surveil” triggers after you’re done surveilling, even if you have fewer cards in your library than the number of cards you’re instructed to surveil. It triggers even if you have no cards in your library.
- 2 February 2024The token doesn’t copy whether Copy Catchers is tapped or untapped, whether it has any counters on it or Auras attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.
- 2 February 2024In the unusual case where Copy Catchers becomes a copy of something else while its triggered ability is on the stack but before it resolves, the token will enter the battlefield as a copy of whatever Copy Catchers is copying. (Do you copy? Over.)
- 2 February 2024The token copy will have Copy Catchers’s abilities and will be able to create copies of itself.
- 2 February 2024If Copy Catchers leaves the battlefield before its triggered ability resolves, the token will still enter the battlefield as a copy of Copy Catchers, using Copy Catchers’s copiable values from when it was last on the battlefield.
