Prosper, Tome-Bound + Goldspan Dragon + Flameskull + Adrix and Nev, Twincasters + Goblin Bombardment

Prosper, Tome-Bound

Goldspan Dragon

Flameskull

Adrix and Nev, Twincasters

Goblin Bombardment

How it works

1. Activate Goblin Bombardment by sacrificing Flameskull.
2. When Flameskull dies, it triggers, exiling it and the top card of your library with the ability to cast one from exile this turn.
3. Resolve the Goblin Bombardment ability.
4. Cast Flameskull from exile by paying 1.
5. Prosper's second ability triggers, creating two Treasure tokens.
6. Activate the Treasures by tapping and sacrificing them, adding 2.
7. Repeat.

This explosive loop centers on the recursive loop of Flameskull, which feeds endlessly into Goblin Bombardment as a convenient sacrifice outlet. Whenever Flameskull dies and triggers its Rejuvenation ability, you get to recast it from exile, turning Prosper, Tome-Bound's Pact Boon into a steady stream of generated wealth. That mana production is significantly supercharged by Goldspan Dragon, which doubles the output of your sacrifices, while Adrix and Nev, Twincasters steps in to double the total number of Treasure tokens created at every single iteration.
