Dross Scorpion + Elemental Mastery + Encroaching Mycosynth + Bartolomé del Presidio

Dross Scorpion

Elemental Mastery

Encroaching Mycosynth

Bartolomé del Presidio

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 Bartolomé del Presidio by sacrificing an Elemental.
3. When the Elemental dies as an artifact due to Encroaching Mycosynth, Dross Scorpion triggers, untapping the creature with Elemental Mastery attached.
4. Resolve the Bartolomé del Presidio ability.
5. Repeat.

This ingenious loop transforms raw army-building power into an unstoppable execution engine by turning your entire board into a machine shop. Enchanting a creature with Elemental Mastery lets it churn out a swarm of hasty tokens, while Encroaching Mycosynth quietly does the heavy lifting behind the scenes by turning every single one of those tokens into an artifact the moment they enter. This means when Bartolomé del Presidio sacrifices an Elemental token, Dross Scorpion sees an artifact creature bite the dust and immediately triggers to untap your mastery-enchanted creature. You can then repeat this cycle endlessly, fueling Bartolomé del Presidio with infinite growth while generating infinite tokens, deaths, and sacrifice triggers.
