Scaretiller + Vesuva + Gods' Eye, Gate to the Reikai + Retreat to Coralhelm + Cryptolith Rite

Scaretiller

Vesuva

Gods' Eye, Gate to the Reikai

Retreat to Coralhelm

Cryptolith Rite

How it works

1. Activate Scaretiller by tapping it, adding one mana of any color.
2. Scaretiller triggers, returning Vesuva from your graveyard to the battlefield as a copy of Gods' Eye.
3. Put Vesuva into your graveyard due to the legend rule.
4. Vesuva and Retreat to Coralhelm trigger.
5. Resolve the Retreat to Coralhelm trigger, untapping Scaretiller.
6. Resolve the Vesuva trigger, creating a 1/1 Spirit creature token.
7. Repeat.

This clever loop turns the unassuming Scaretiller into a self-sustaining engine by utilizing Cryptolith Rite to give it the ability to tap for mana. Each time Scaretiller taps, its triggered ability pulls Vesuva out of your graveyard and onto the battlefield mimicking Gods' Eye, Gate to the Reikai. The legend rule immediately sends your copy of Gods' Eye to the graveyard, triggering both the token generation from Gods' Eye and a landfall trigger from Retreat to Coralhelm. Finally, Retreat to Coralhelm untaps Scaretiller so you can repeat the process, fueling endless colored mana, infinite spirits, and endless landfall triggers.
