Aether Storm + Mindslaver + Quicksilver, Speedster

Aether Storm

Mindslaver

Quicksilver, Speedster

How it works

1. Activate Mindslaver by paying 4 and tapping it, causing you to gain control of target opponent during their next turn.
2. During the opponent's turn, cast Aether Storm by paying 3.
3. As the opponent, activate Aether Storm by paying 4 life.
4. Repeat step 3 until the opponent has 3 or less life remaining.

By seizing control of your opponent during their turn with Mindslaver, you gain the agency needed to turn their own resources against them. With Quicksilver, Speedster on the battlefield, its static ability lets you cast spells as though they had flash even on your opponent's turn, allowing you to deploy Aether Storm into their hands. Once it resolves, Aether Storm's static restriction normally locks down creature spells, but its active ability is the true engine here: because you are controlling the opponent, you can repeatedly force them to pay 4 life to destroy the enchantment, draining their life total down to nothing in a brutal display of alchemical manipulation.
