Dross Scorpion + Elemental Mastery + Blasting Station + Mycosynth Lattice

Dross Scorpion

Elemental Mastery

Blasting Station

Mycosynth Lattice

How it works

1. Activate the creature with Elemental Mastery attached by tapping it, creating a number of 1/1 Elemental creature tokens with haste equal to its power.
2. When the Elementals enter, Blasting Station triggers that many times, untapping Blasting Station.
3. Activate Blasting Station by tapping it and sacrificing an Elemental.
4. When the Elemental dies as an artifact due to Mycosynth Lattice, Dross Scorpion triggers, untapping the creature with Elemental Mastery attached.
5. Resolve the Blasting Station ability.
6. Repeat.

By weaving Mycosynth Lattice into the setup, every permanent on the battlefield—including your creatures—becomes an artifact, turning a simple token-making engine into a lethal loop. When you tap the creature enchanted with Elemental Mastery, it floods the board with hasty tokens that trigger Blasting Station's untap ability while also being treated as artifacts thanks to the Lattice. Sacrificing one of those newly minted artifact tokens to Blasting Station causes it to die, which immediately wakes up Dross Scorpion to untap your creature with Elemental Mastery attached so you can do it all over again. Blasting Station then finishes the opponent off through an endless barrage of damage fueled entirely by this recursive loop of metal and magic.
