Prosper, Tome-Bound + Goldspan Dragon + Flameskull + Anointed Procession + Goblin Bombardment

Prosper, Tome-Bound

Goldspan Dragon

Flameskull

Anointed Procession

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 brilliant engine turns a simple recursive loop into a massive treasure trove by leveraging the synergy between the graveyard, exile, and token multipliers. You begin by sacrificing Flameskull to Goblin Bombardment, which triggers its Rejuvenation ability to exile itself alongside the top card of your library while sending it back to your hand-equivalent exile zone. When you cast Flameskull from exile, Prosper, Tome-Bound's Pact Boon ability triggers to generate a Treasure token, which is immediately doubled into two Treasures thanks to Anointed Procession's replacement effect. Goldspan Dragon then supercharges those generated tokens so that each sacrifices for two mana instead of one, perfectly refunding the cost to recast Flameskull with mana to spare.
