Toph, the First Metalbender + Toph, Hardheaded Teacher + Thaumatog + Gruul Turf

Toph, the First Metalbender

Toph, Hardheaded Teacher

Thaumatog

Gruul Turf

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Gruul Turf.
3. Resolve the artifact spell.
4. Activate Thaumatog by sacrificing Gruul Turf.
5. When Gruul Turf dies, Toph, Hardheaded Teach triggers, returning Gruul Turf from your graveyard to the battlefield tapped.
6. When Gruul Turf enters, it triggers, returning the artifact cast in step 1 from the battlefield to your hand, as it's a land due to Toph, the First Metalbender.
7. Resolve the Thaumatog ability
8. Repeat.

This ingenious loop relies on turning your artifacts into lands using Toph, the First Metalbender, which brilliantly allows Gruul Turf's landfall-style bounce trigger to scoop up your free artifact right back to your hand. Meanwhile, Thaumatog acts as the sacrifice outlet that bins Gruul Turf, triggering Toph, Hardheaded Teacher to instantly recursion-pull the land right back to the battlefield tapped. Each time Gruul Turf re-enters, it bounces the artifact you just recast, fueling an endless chain of artifact and land movements while pumping Thaumatog to staggering proportions.
