6 rulings from Wizards of the Coast
- 4 October 2004Treat the token as entering as a copy of the chosen creature. If that creature normally gets counters when entering, the token creature gets counters.
- 4 October 2004The ability is targeted and checks the validity of the target when put on the stack and when resolving. If the creature is not still there when the copy ability resolves, the ability doesn't resolve and no token is put onto the battlefield. This card remains on the battlefield as an enchantment with no token.
- 4 October 2004Destroying the creature that was copied will not cause the token creature to be destroyed as well.
- 4 October 2004The mana cost is copied.
- 4 October 2004Each Dance of Many is associated only with its token creature. If one Dance leaves the battlefield, only the corresponding token is affected, not all tokens from all instances of Dance of Many.
- 1 October 2009If Dance of Many leaves the battlefield before its first ability has resolved, its second ability will trigger and do nothing. Then its first ability will resolve and put a token onto the battlefield. That token won't have any connection to a Dance of Many permanent, so it won't be exiled when a Dance of Many leaves the battlefield.
