5 rulings from Wizards of the Coast
- 10 November 2020The control-change effect of Blim's ability lasts indefinitely. It doesn't wear off during the cleanup step, and it doesn't expire if Blim leaves the battlefield. In a multiplayer game, it does expire if the current controller leaves the game.
- 10 November 2020If the target permanent you control is an illegal target by the time Blim's ability tries to resolve, the ability doesn't resolve. The other player doesn't gain control of your permanent, and no one loses life or discards cards.
- 10 November 2020Players lose life and discard cards for all permanents they control but don't own, not just the ones they received from you.
- 10 November 2020The player who was dealt damage can't refuse your generous gift. That would be rude.
- 10 November 2020You choose which permanent the player gains control of, not the player who was dealt damage.
