Impostor Syndrome + Fear of Missing Out + Fervor

Impostor Syndrome

Fear of Missing Out

Fervor

How it works

1. Declare Fear of Missing Out as an attacker, triggering its ability, causing you to untap it and to get an additional combat phase after this one.
2. Deal combat damage to an opponent using Fear of Missing Out, triggering Impostor Syndrome, creating a token copy of Fear of Missing Out that isn't legendary.
3. When the Fear of Missing Out token enters, it triggers, causing you to rummage
4. During your next combat phase, declare Fear of Missing Out and the Fear of Missing Out token as attackers.
5. The Fear of Missing Out token triggers, causing you to untap the nontoken Fear of Missing Out and to get an additional combat phase after this one.
6. Repeat from step 2.

This brilliant loop turns a single attacker into an ever-multiplying army of bonus combat steps, fueled entirely by combat damage and graveyard threshold. With Fervor granting your team haste, each new copy created by Impostor Syndrome can immediately join the fray without waiting around. As those copies of Fear of Missing Out flood the battlefield, their entry triggers cycle through your hand while their delirium-fueled attacks keep chaining additional combat phases together indefinitely.
