Mikaeus, the Unhallowed + Blue, Loyal Raptor + Shilgengar, Sire of Famine

Mikaeus, the Unhallowed

Blue, Loyal Raptor

Shilgengar, Sire of Famine

How it works

1. Activate Shilgengar 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 Shilgengar ability.
4. Repeat.
