Mishra, Eminent One + The Master, Multiplied + Hesitation + Liquimetal Torque

Mishra, Eminent One

The Master, Multiplied

Hesitation

Liquimetal Torque

How it works

1. Activate Liquimetal Torque's second ability by tapping it, causing Hesitation to become an artifact until end of turn.
2. At the beginning of your combat phase, Mishra triggers, creating a token copy of Hesitation that is a 4/4 artifact creature named Mishra's Warform in addition to its other types.
3. At the beginning of your end step, Mishra's Warform triggers, causing you to fail to sacrifice Mishra's Warform due to The Master.
4. Whenever a player casts a spell, Mishra's Warform triggers, countering that spell and causing you to fail to sacrifice it due to The Master.
5. Repeat step 4 as necessary.

This intricate lock relies on transforming nonartifact nuisances like Hesitation into viable targets for Mishra, Eminent One, which turns them into 4/4 Mishra's Warform token copies during combat. Normally, these tokens would be doomed to vanish or force a sacrifice, but The Master, Multiplied steps in with its passive ability to cleanly bypass any sacrifice restrictions. Best of all, Liquimetal Torque keeps the engine fueled by turning permanents into artifacts on demand, letting your immortal Mishra's Warform token repeatedly trigger to counter every spell your opponents try to cast without ever having to pay the ultimate price.
