The Master, Multiplied + Lunar Force + Kaya, Intangible Slayer

The Master, Multiplied

Lunar Force

Kaya, Intangible Slayer

How it works

1. Activate Kaya's third loyalty ability by removing three loyalty counters from it, exiling Lunar Force and creating a token copy of it that is a 1/1 Spirit in addition to its other types.
2. Whenever an opponent casts a spell, the Lunar Force token triggers, countering that spell and causing you to fail to sacrifice it due to The Master.
3. Repeat step 2 as necessary.
