Blightbeetle + Viscera Seer + Coveted Falcon

Blightbeetle

Viscera Seer

Coveted Falcon

How it works

1. Activate Coveted Falcon by paying 1, turning it face up.
2. Coveted Falcon triggers, causing an opponent to gain control of Blightbeetle and causing you to draw a card.
3. Activate Viscera Seer by sacrificing the undying creature.
4. When the undying creature dies, its undying ability triggers, returning itself from your graveyard to the battlefield without a +1/+1 counter on it due to Blightbeetle.
5. Resolve the Viscera Seer ability.
6. Repeat from step 3.

This crafty loop turns a classic recursion engine into an endless well of triggers, anchored by a secret benefactor that makes the whole thing work. While Viscera Seer provides the sacrifice outlet to send your creature to the graveyard, Blightbeetle's passive ability steps in to prevent your creature from receiving +1/+1 counters upon its return, allowing its undying persistence to trigger infinitely. Meanwhile, Coveted Falcon acts as your card-drawing engine and battlefield currency, using its disguise flip ability to hand over unwanted permanents while churning through your library one draw at a time.
