14 rulings from Wizards of the Coast
- 14 April 2023Once you’ve cast See Double and legally chosen both modes, it doesn’t matter what happens to the number of cards in opponents’ graveyards.
- 14 April 2023If the spell that’s copied is modal (that is, it includes a choice from a bulleted list of effects), the copy will have the same mode. A different mode can’t be chosen.
- 14 April 2023If the copied creature is copying something else, then the token enters the battlefield as whatever that creature copied.
- 14 April 2023The token copies exactly what was printed on the original creature and nothing else (unless that creature is copying something else or is a token; see below). It doesn’t copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.
- 14 April 2023If the copied creature has {X} in its mana cost, X is 0.
- 14 April 2023If the copied creature is a token, the token that’s created copies the original characteristics of that token as stated by the effect that created that token.
- 14 April 2023If the spell that’s copied has an X whose value was determined as it was cast, the copy will have the same value of X.
- 14 April 2023You may choose both modes if any opponent has eight or more cards in their graveyard, not necessarily all of them.
- 14 April 2023If the spell has damage divided as it was cast, the division can’t be changed (although the targets receiving that damage still can). The same is true of spells that distribute counters.
- 14 April 2023Any enters-the-battlefield abilities of the copied creature will trigger when the token enters the battlefield. Any “as [this creature] enters the battlefield” or “[this creature] enters the battlefield with” abilities of the copied creature will also work.
- 14 April 2023You can’t choose to pay any alternative or additional costs for the copy of the spell. However, effects based on any alternative or additional costs that were paid for the original spell are copied as though those same costs were paid for the copy.
- 14 April 2023The copy will have the same targets as the spell it’s copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can’t choose a new legal target, then it remains unchanged (even if the current target is illegal).
- 14 April 2023A copy of a spell is created on the stack, so it’s not “cast.” Abilities that trigger when a player casts a spell won’t trigger.
- 14 April 2023If you copy a spell, you control the copy. It will resolve before the original spell does.
