• Jul 12, 2019 A token's owner is the player who created it.
• Jul 12, 2019 Agent of Treachery's effect lasts indefinitely. It doesn't wear off during the cleanup step, and it doesn't expire if Agent of Treachery leaves the battlefield. In a multiplayer game, it does expire if you leave the game.
• Jul 12, 2019 Gaining control of a creature doesn't cause you to gain control of any Auras or Equipment attached to it. Gaining control of an Aura or Equipment doesn't change what it's currently attached to.
• Jul 12, 2019 If you don't control three permanents you don't own as your end step begins, Agent of Treachery's last ability doesn't trigger. If you no longer control three permanents you don't own as it resolves, you won't draw three cards. Those don't have to be the same three permanents each time.
• Jul 12, 2019 If you gain control of a permanent "until end of turn," that effect will wear off during the cleanup step, after the end step. You'll control that permanent while considering Agent of Treachery's last ability.
