Dross Scorpion + Elemental Mastery + Ashnod's Altar + Biotransference

Dross Scorpion

Elemental Mastery

Ashnod's Altar

Biotransference

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. Activate Ashnod's Altar by sacrificing an Elemental.
3. When the Elemental dies as an artifact due to Biotransference, Dross Scorpion triggers, untapping the creature with Elemental Mastery attached.
4. Repeat.

This ingenious loop turns your creature into a relentless token-generating engine, fueled entirely by the synergy of Biotransference turning your entire squad into artifact creatures. When you tap the enchanted creature using Elemental Mastery, you flood the board with haste-granting tokens whose power matches your creature's. You then feed those freshly minted tokens into Ashnod's Altar to generate a steady stream of colorless mana. Crucially, because Biotransference makes all your creatures into artifacts, each sacrifice triggers Dross Scorpion, which immediately untaps your master token-producer so the cycle can begin anew.
