Mikaeus, the Unhallowed + Viscera Seer + Brambleback Brute

Mikaeus, the Unhallowed

Viscera Seer

Brambleback Brute

How it works

1. Activate Viscera Seer 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 Viscera Seer ability
4. Repeat.
