Prosper, Tome-Bound + Goldspan Dragon + Flameskull + Umbral Collar Zealot + Parallel Lives

Prosper, Tome-Bound

Goldspan Dragon

Flameskull

Umbral Collar Zealot

Parallel Lives

How it works

1. Activate Umbral Collar Zealot 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 Umbral Collar Zealot 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 loop is a masterclass in recycling, turning the self-returning Flameskull into a relentless engine of creation. By using Umbral Collar Zealot to sacrifice Flameskull, you trigger the skull's own Rejuvenation ability alongside the mana-doubling benefits of Goldspan Dragon. The real magic happens because Prosper, Tome-Bound spots you casting the skull from exile and rewards you with Treasure tokens, whose output is instantly doubled by Parallel Lives. Goldspan Dragon then ensures those doubled Treasures punch far above their weight class by tapping for two mana each, effortlessly footing the bill to recast Flameskull and keep the cycle spinning infinitely.
