Dross Scorpion + Elemental Mastery + Biotransference + Bloodflow Connoisseur

Dross Scorpion

Elemental Mastery

Biotransference

Bloodflow Connoisseur

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 Bloodflow Connoisseur 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. Resolve the Bloodflow Connoisseur ability.
5. Repeat.

This loop transforms your enchanted creature into a token-producing engine, fueled by Biotransference turning every creature you control into an artifact. When you tap the creature using Elemental Mastery, it floods the board with hasty tokens, while Bloodflow Connoisseur stands ready to consume them for growing power. Every time a sacrificed token dies, Dross Scorpion's static death trigger notices an artifact hitting the graveyard and immediately untaps your master of ceremonies, readying it to tap again and repeat the cycle.
