Devilish Valet + Pemmin's Aura + Elemental Mastery

Devilish Valet

Pemmin's Aura

Elemental Mastery

How it works

1. Activate Devilish Valet by tapping it, creating a number of 1/1 Elemental creature tokens with haste equal to its power.
2. When the Elementals enter the battlefield, Devilish Valet triggers that many times.
3. Resolve the first trigger, doubling Devilish Valet's power until end of turn.
4. Repeat step 3 for each remaining trigger.
5. Activate Pemmin's Aura's first ability by paying , untapping Devilish Valet.
6. Repeat as desired, or as persists.

This clever engine turns Devilish Valet into an exponential powerhouse by leveraging its native alliance ability. When you enchant the Valet with Elemental Mastery, tapping it churns out an army of 1/1 Elemental tokens whose numbers scale directly with its current massive strength. Every single one of those tokens entering the battlefield triggers the Valet's alliance property anew, doubling its power exponentially with each resolving stack item. To keep the chain going, Pemmin's Aura provides the crucial untap ability for just a blue mana, allowing you to untap the Valet and repeat the entire tap-and-create cycle for near-infinite tokens, unending enter-the-battlefield triggers, and astronomical power.
