The Master, Multiplied + Cybermen Squadron + Mycosynth Lattice + Combat Celebrant

The Master, Multiplied

Cybermen Squadron

Mycosynth Lattice

Combat Celebrant

How it works

1. Declare Combat Celebrant as an attacker, choosing to exert it as it attacks.
2. Combat Celebrant's myriad and printed abilities trigger.
3. Resolve the myriad trigger, creating a token copy of Combat Celebrant attacking each other opponent.
4. Resolve the second trigger, causing you to untap all other creatures you control and to get an additional combat phase after this one.
5. Move to your next combat phase, not exiling the Combat Celebrant tokens due to The Master.
6. Repeat using a Combat Celebrant token that hasn't attacked this turn.

By turning every permanent on the battlefield into an artifact with Mycosynth Lattice, you ensure that Cybermen Squadron grants myriad to your entire team—including Combat Celebrant. When you declare Combat Celebrant as an attacker and exert it, its myriad ability floods the board with attacking token copies while its own triggered ability grants you an additional combat phase and untaps your creatures. Ordinarily, those tokens would be exiled at the end of combat, but The Master, Multiplied steps in with its passive ability to completely shut down any sacrifices or exiles affecting your creature tokens. This allows your exponential army of Combat Celebrants to stick around, bypass the legend rule entirely, and continuously repeat the process for infinite combat phases.
