Mikaeus, the Unhallowed + Goblin Bombardment + Obstinate Gargoyle

Mikaeus, the Unhallowed

Goblin Bombardment

Obstinate Gargoyle

How it works

1. Activate Goblin Bombardment by sacrificing Obstinate Gargoyle.
2. When Obstinate Gargoyle dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. Resolve the Goblin Bombardment ability.
4. Activate Goblin Bombardment by sacrificing Obstinate Gargoyle.
5. When Obstinate Gargoyle dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
6. Resolve the Goblin Bombardment ability.
7. Repeat.

This clever loop exploits the fascinating interaction between conflicting counters to recycle Obstinate Gargoyle indefinitely. Because Mikaeus, the Unhallowed grants the Gargoyle undying, while the Gargoyle's own native persist ability brings it back with a -1/-1 counter, the two counters perpetually cancel each other out upon subsequent deaths rather than locking the creature out of returning. Goblin Bombardment provides the reliable sacrifice outlet to trigger this cycle on demand, converting the endless loop of resurrections into an infinite stream of damage.
