Mikaeus, the Unhallowed + Blue, Loyal Raptor + Viscera Seer

Mikaeus, the Unhallowed

Blue, Loyal Raptor

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing the other Dinosaur.
2. When the Dinosaur dies, its undying ability triggers, returning it from your graveyard to the battlefield without a +1/+1 counter on it due to the -1/-1 counter it will gain from Blue.
3. Resolve the Viscera Seer ability.
4. Repeat.

This brilliant loop turns your battlefield into an endless cycle of sacrifice and rebirth by weaponizing a clever rules interaction. While Viscera Seer provides the free sacrifice outlet to bin your creatures, Mikaeus, the Unhallowed grants them undying to bring them right back to life. The linchpin of the strategy is Blue, Loyal Raptor: because Blue endows other Dinosaurs with its counters upon entry, it ensures the sacrificed Dinosaur enters with a counter that cancels out Mikaeus's undying counter, allowing the loop to repeat indefinitely for infinite sacrifice and death triggers.
