Mikaeus, the Unhallowed + Defiant Greatmaw + Blasting Station

Mikaeus, the Unhallowed

Defiant Greatmaw

Blasting Station

How it works

1. Activate Blasting Station by tapping it and sacrificing Defiant Greatmaw.
2. When Defiant Greatmaw dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. When Defiant Greatmaw enters the battlefield, its first ability and Blasting Station trigger.
4. Resolve the Defiant Greatmaw trigger, putting two -1/-1 counters on it.
5. Defiant Greatmaw's second ability triggers, removing a -1/-1 counter from another creature you control.
6. Resolve the Blasting Station trigger from step 3, untapping it.
7. Resolve the Blasting Station ability from step 1, dealing 1 damage to any target.
8. Repeat.

This ingenious loop harnesses Mikaeus, the Unhallowed to grant undying to other non-Human creatures, turning the graveyard into a revolving door for Defiant Greatmaw. Every time Defiant Greatmaw enters the battlefield, it triggers Blasting Station, which can then be used to sacrifice the Greatmaw itself and pelt your opponents with damage. Because Mikaeus's lord buff provides the crucial +1/+1 counter on return while Defiant Greatmaw's own enters-the-battlefield ability places -1/-1 counters to instantly strip it away, the counter math self-corrects indefinitely to keep the cycle alive.
