Oracle Text

Enchant creature

Card Rulings

3/16/2018 The enchanted creature is the source of both the damage ability and the resultant damage, not Quicksilver Dagger. For example, if Quicksilver Dagger and Curiosity enchant the same creature, Curiosity’s ability will trigger when the damage is dealt.
