Karn's Time Capsule

Indestructible
When Karn's Time Capsule enters the
battlefield, put a Capsule counter on each other
non-token permanent you control. If a
permanent with a Capsule counter on it would
leave the battlefield, exile it instead.
If you would lose the game, instead exile Karn's
Time Capsule and return all permanents to the battlefield exiled with Karn's Time Capsule.
Your life total becomes 10.
