Dross Scorpion + Elemental Mastery + Woe Strider + Biotransference

Dross Scorpion

Elemental Mastery

Woe Strider

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 Woe Strider 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 Woe Strider ability.
5. Repeat.

This loop transforms your battlefield into an unstoppable engine by leveraging Biotransference to turn every creature you control—including the hasty tokens—into an artifact. With this typing in place, sacrificing one of those tokens to Woe Strider triggers Dross Scorpion, which automatically untaps the creature enchanted by Elemental Mastery so you can tap it again to flood the board with more fodder. This creates a closed circuit of endless sacrifices, scry triggers, and hasty elementals ready to fuel the cycle all over again.
