Mikaeus, the Unhallowed + Shilgengar, Sire of Famine + Brambleback Brute

Mikaeus, the Unhallowed

Shilgengar, Sire of Famine

Brambleback Brute

How it works

1. Activate Shilgengar by sacrificing Brambleback Brute.
2. When Brambleback Brute dies, its undying ability triggers, returning it from your graveyard to the battlefield without a +1/+1 counter on it due to its replacement effect.
3. Resolve the Shilgengar ability
4. Repeat.
