Karn Liberated

No actions taken in the game that was restarted apply to the new game. For example, if you were dealt damage by Stigma Lasher in the original game, the effect that states you can't gain life doesn't carry over to the new game.

Permanents put onto the battlefield due to Karn's ability will have been under the starting controller's control continuously since the beginning of that player's first turn. Creatures among them can attack and their activated abilities with {T} in the cost can be activated.

Karn's first and third abilities are linked. Similarly, Karn's second and third abilities are linked. Only non-Aura permanent cards exiled by either of Karn's first two abilities will remain in exile when the game restarts.

After the pregame procedure is complete but before the new game's first turn, Karn's ability finishes resolving and the cards left in exile are put onto the battlefield. If this causes any triggered abilities to trigger, those abilities are put onto the stack at the beginning of the first upkeep step.

Players won't have any counters or emblems they had in the original game.

A game that restarts immediately ends the preceding game. The players in that game then immediately begin a new game. No player wins, loses, or draws the original game as a result of Karn's ability.
