9 rulings from Wizards of the Coast
- 2 February 2024The copies of Follow the Bodies created by its gravestorm ability are created on the stack, so they're not cast and won't cause abilities that trigger when a player casts a spell to trigger.
- 2 February 2024Gravestorm counts all permanents put into graveyards from the battlefield this turn. It doesn't matter who controlled those permanents, who owns them, or whether or not they were tokens.
- 2 February 2024You can't sacrifice a Clue to pay multiple costs. For example, you can't sacrifice a Clue token to activate its own ability and also to activate Alquist Proft, Master Sleuth's ability.
- 2 February 2024Some abilities trigger "whenever you sacrifice a Clue". Those abilities trigger whenever you sacrifice a Clue for any reason, not just to activate a Clue's activated ability.
- 2 February 2024Clue is an artifact type. Even though it appears on some cards with other permanent types, it's never a creature type, a land type, or anything but an artifact type.
- 2 February 2024Some spells and abilities that investigate may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. You won't create any Clue tokens.
- 2 February 2024If an effect refers to a Clue, it means any Clue artifact, not just a Clue artifact token. For example, you can sacrifice Wrench to pay for Alquist Proft, Master Sleuth's activated ability.
- 2 February 2024The triggered ability that creates the copies can itself be countered by anything that can counter a triggered ability. If it is countered, no copies will be put onto the stack.
- 2 February 2024A copy of a spell can be countered like any other spell, but it must be countered individually. Countering a spell with gravestorm won't affect the copies.
