Mikaeus, the Unhallowed + Woe Strider + Pith Driller

Mikaeus, the Unhallowed

Woe Strider

Pith Driller

How it works

1. Activate Woe Strider by sacrifiicing Pith Driller.
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. Resolve the Woe Strider ability, causing you to scry 1.
5. Repeat.

This clever loop relies on Mikaeus, the Unhallowed to grant the undying ability to your other non-Human creatures, turning any suitable sacrifice subject into a recurring engine. By feeding Pith Driller to Woe Strider's sacrifice ability, you send the horror straight to the graveyard only to watch it immediately return thanks to Mikaeus. Because Pith Driller enters the battlefield with a -1/-1 counter from its own triggered ability, that counter immediately neutralizes the +1/+1 counter it would receive from undying, resetting its state so the loop can repeat indefinitely for boundless sacrifices and scry triggers.
