Mikaeus, the Unhallowed + Thermopod + Pith Driller

Mikaeus, the Unhallowed

Thermopod

Pith Driller

How it works

1. Activate Thermopod's second ability by sacrificing Pith Driller, adding .
2. When Pith Driller dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. When Pith Driller enters the battlefield, it triggers, putting a -1/-1 counter on it.
4. Repeat.

This ingenious loop transforms a seemingly modest phyrexian-mana creature into an endless engine by leveraging the passive gifts of Mikaeus, the Unhallowed, whose presence grants your non-Human creatures the undying keyword to constantly bring them back from the grave. When you sacrifice Pith Driller to Thermopod for red mana, undying returns it with a +1/+1 counter, but Pith Driller's own entry trigger immediately places a -1/-1 counter on itself. Because state-based actions neutralize matching +1/+1 and -1/-1 counters by removing one of each, Pith Driller is left completely counter-free—allowing undying to trigger all over again for an infinite cycle of sacrifices and mana.
