Undercity Scrounger + Pemmin's Aura + Doubling Season

Undercity Scrounger

Pemmin's Aura

Doubling Season

How it works

1. Activate Undercity Scrounger by tapping it, creating two Treasure tokens.
2. Activate a Treasure token by tapping and sacrificing it, adding .
3. Activate Pemmin's Aura's first ability by paying , untapping Undercity Scrounger.
4. Repeat.

This loop transforms a modest construct into an engine for infinite mana and treasures by exploiting a clever numerical advantage. By enchanting **Undercity Scrounger** with **Pemmin's Aura**, you gain the ability to untap the creature for a single blue mana, but the Scrounger's tap normally produces only a single Treasure token and requires a dead creature. Enter **Doubling Season**: its replacement effect doubles the token generation of the Scrounger's tap ability into two Treasures instead of one, bypassing the need for actual casualties while generating a net positive of mana when you sacrifice one Treasure to pay for the Aura's untap cost.
