- 1 August 2008The targeted creature’s controller, not Banishing Knack’s controller, is the one who can activate the creature’s new ability.
- 1 August 2008“Summoning sickness” applies. The new ability can’t be activated unless the targeted creature has been under its controller’s control since the beginning of that player’s most recent turn or it has haste.
