Impostor Syndrome + Combat Celebrant + Samut, Voice of Dissent

Impostor Syndrome

Combat Celebrant

Samut, Voice of Dissent

How it works

1. Declare Combat Celebrant as an attacker, choosing to exert it as it attacks and triggering its ability, causing you to untap all other creatures you control and to get an additional combat phase after this one.
2. Deal combat damage to an opponent using Combat Celebrant, triggering Impostor Syndrome, creating a token copy of Combat Celebrant that isn't legendary.
3. During your next combat phase, declare Combat Celebrant and the Combat Celebrant token as attackers, choosing to exert the Combat Celebrant token as it attacks.
4. The Combat Celebrant token triggers, causing you to untap all other creatures you control and to get an additional combat phase after this one.
5. Repeat from step 2.

This relentless assault loops infinitely by leveraging Combat Celebrant's exert ability to repeatedly grant you additional combat phases, all while Impostor Syndrome steps in to multiply your attackers every time they deal combat damage. Because Impostor Syndrome creates non-legendary token copies of your damaging creatures, every new iteration brings another Combat Celebrant into the fray to keep the chain going. Meanwhile, Samut, Voice of Dissent sits comfortably in the background providing static haste to ensure your newly minted token copies can immediately attack during the extra combat phases, and can even use her activated ability to untap your key pieces if needed.
