Mikaeus, the Unhallowed + Resourceful Defense + Dockside Extortionist + Blasting Station

Mikaeus, the Unhallowed

Resourceful Defense

Dockside Extortionist

Blasting Station

How it works

1. Activate Blasting Station by tapping it and sacrificing Dockside Extortionist.
2. When Dockside Extortionist dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. When Dockside Extortionist enters the battlefield, it and Blasting Station trigger.
4. Resolve the Blasting Station trigger, untapping it.
5. Resolve the Dockside Extortionist trigger, creating at least five Treasure artifact tokens.
6. Resolve the Blasting Station ability from step 1, dealing 1 damage to any target.
7. Activate five Treasures by tapping and sacrificing them, adding 4.
8. Activate Resourceful Defense by paying 4, moving all +1/+1 counters from Dockside Extortionist onto another permanent you control.
9. Repeat.
10. If opponents control six or more artifacts and/or enchantments, this combo nets infinite Treasure tokens and colored mana.

This loop turns Dockside Extortionist into an endless loop of sacrifices and returns by leveraging Mikaeus, the Unhallowed to grant undying, ensuring the goblin comes back with a +1/+1 counter each time Blasting Station flings it for damage. Normally, that counter would permanently shut down further undying triggers, but Resourceful Defense cleverly rescues the situation by moving those pesky counters off the Extortionist the moment they land, resetting its state. Meanwhile, Blasting Station's untap ability keeps the firing chamber ready, and the copious treasures generated by Dockside Extortionist easily pay for the enchantment's manual counter-moving ability while netting an endless surplus of mana and damage.
