Toggo, Goblin Weaponsmith + Scaretiller + Clock of Omens + Obscura Storefront

Toggo, Goblin Weaponsmith

Scaretiller

Clock of Omens

Obscura Storefront

How it works

1. Activate Clock of Omens by tapping Scaretiller and another artifact, targeting Scaretiller.
2. Scaretiller triggers, returning Obscura Storefront from your graveyard to the battlefield.
3. Obscura Storefront enters the battlefield, triggering itself and Toggo.
4. Resolve the Toggo trigger, creating a Rock equipment token.
5. Resolve the Obscura Storefront trigger, causing you to sacrifice it then search your library for a basic Island, Plains, or Swamp and put it onto the battlefield.
6. If you put a land onto the battlefield this way, Toggo triggers, creating a Rock equipment token.
7. Resolve the Clock of Omens ability from step 1, untapping Scaretiller.
8. Repeat.
