3 rulings from Wizards of the Coast
- 25 January 2019In a multiplayer game, if a player leaves the game, all cards that player owns leave as well. If you leave the game, the effect giving you control of the target nonland permanent ends.
- 25 January 2019The effect of Eyes Everywhere’s last ability lasts indefinitely. It doesn’t wear off during the cleanup step, and it doesn’t expire if Eyes Everywhere leaves the battlefield.
- 25 January 2019As Eyes Everywhere’s last ability resolves, Eyes Everywhere must be on the battlefield and the target nonland permanent must be a legal target. If either of these things isn’t true, the ability does nothing.
