Mindslaver + Lethal Vapors + Vedalken Orrery

Mindslaver

Lethal Vapors

Vedalken Orrery

How it works

1. Activate Mindslaver by paying 4, tapping and sacrificing it, causing you to gain control of target opponent during their next turn.
2. During the opponent's turn, cast Lethal Vapors by paying 2.
3. As the opponent, activate Lethal Vapors by paying 0 an arbitrarily large number of times, causing that opponent to skip that many turns.

This deliciously cruel lock begins by seizing absolute control of your opponent's destiny using Mindslaver. With Vedalken Orrery granting you flash, you drop Lethal Vapors directly onto the battlefield during their stolen turn. Because Lethal Vapors allows *any* player to activate its ability, you can repeatedly use its {0} cost to skip the controlled player's turns as many times as you like. Since the turn-skip penalty stacks indefinitely, you effectively exile that player from the game, leaving them helpless while you take all the time you need to finish them off.
