Mikaeus, the Unhallowed + Kaervek, the Spiteful + Tatterkite + Night of Souls' Betrayal

Mikaeus, the Unhallowed

Kaervek, the Spiteful

Tatterkite

Night of Souls' Betrayal

How it works

1. Cast Tatterkite by paying 3.
2. Tatterkite enters the battlefield and dies as a state-based action due to having 0 toughness.
3. Tatterkite's undying ability triggers, returning it from your graveyard to the battlefield with zero +1/+1 counters on it due to its effect.
4. Repeat from step 2.
5. NOTE: This combo creates a mandatory infinite loop that will draw the game if it isn't interacted with.
