Mikaeus, the Unhallowed + Spike Feeder + Viscera Seer

Mikaeus, the Unhallowed

Spike Feeder

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Spike Feeder.
2. Spike Feeder's undying ability triggers, returning itself to the battlefield with a +1/+1 counter on it.
3. Resolve the Viscera Seer ability, causing you to scry 1.
4. Activate Spike Feeder's second ability three times by removing three +1/+1 counters from it, causing you to gain six life.
5. Repeat.

This elegant loop relies on Mikaeus, the Unhallowed to grant undying to Spike Feeder, ensuring it returns from the grave with a +1/+1 counter whenever it dies. You can immediately sacrifice Spike Feeder to Viscera Seer to trigger that undying return while utilizing Viscera Seer's sacrifice outlet to churn through your library with infinite scrys. Because Spike Feeder can remove its own counters for life, you are free to reset its counter status as needed, keeping the cycle going indefinitely.
