Sami, Wildcat Captain + Meticulous Excavation + Sceptre of Eternal Glory

Sami, Wildcat Captain

Meticulous Excavation

Sceptre of Eternal Glory

How it works

1. Cast Sceptre of Eternal Glory by paying 0 due to Sami.
2. Activate Sceptre of Eternal Glory's second ability by tapping it, adding .
3. Activate Meticulous Excavation by paying 2, returning Sceptre of Eternal Glory from the battlefield to your hand.
4. Repeat.

This clever loop turns the cost reduction from Sami, Wildcat Captain's affinity for artifacts ability into a complete engine by letting you cast Sceptre of Eternal Glory for free. Once it's on the battlefield, you can tap it to generate three mana using its second ability, which easily covers the activation cost of Meticulous Excavation. Paying to return the Sceptre to your hand with Meticulous Excavation clears the way to cast it for zero mana once again, generating an endless cycle of entering and leaving the battlefield.
