Mikaeus, the Unhallowed + Canker Abomination + Umbral Collar Zealot

Prerequisites

• An opponent controls a creature.

Steps

1. 1Activate Umbral Collar Zealot by sacrificing Canker Abomination.
2. 2When Canker Abomination dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. 3When Canker Abomination enters the battlefield, it triggers, putting a number of -1/-1 counters on it equal to the number of creatures an opponent controls.
4. 4If the opponent had seven or more creatures, Canker Abomination will die as a state-based action due to having 0 or less toughness. If this occurs, repeat steps 2 through 4 infinitely.
5. 5Otherwise, resolve the Umbral Collar Zealot ability, and repeat from step 1.
