Mindslaver + Mages' Contest

Mindslaver

Mages' Contest

How it works

1. Activate Mindslaver targeting another player.
2. On their turn, have them cast a spell.
3. In response, cast Mages' Contest targeting the spell they cast.
4. Have them pay their entire life total to Mages' Contest, killing them.

This delightfully sinister interaction turns an opponent's own resources against them in the most literal way possible. By using Mindslaver, you take the helm of target player during their next turn, gaining total control over their decisions, hand, and resources. Once they are forced to cast a spell under your watch, you respond by casting Mages' Contest targeting that spell. Because you are controlling their choices for the turn, you can have them bid their entire life total in the ensuing life-bidding war, causing them to lose the game on the spot.
