Roxanne, Starfall Savant + Basalt Monolith + Replication Specialist

Roxanne, Starfall Savant

Basalt Monolith

Replication Specialist

How it works

1. Cast Basalt Monolith by paying 3.
2. When Basalt Monolith enters the battlefield, Replication Specialist triggers, causing you to pay 1 to create a token copy of Basalt Monolith.
3. Activate the token Basalt Monolith's first ability by tapping it, adding CCC.
4. Roxanne's second ability triggers, adding C.
5. Activate the token Basalt Monolith's second ability by paying 3, untapping it.
6. Repeat from step 3.

This loop relies on a clever interplay of mana-generation and permanent replication, beginning with Basalt Monolith entering the battlefield to trigger Replication Specialist and immediately commission a token copy. While the original Basalt Monolith sits out your untap steps, tapping your token copy for three colorless mana doesn't just fund its own three-mana untap ability; Roxanne, Starfall Savant steps in with her passive mana-doubling whenever you tap an artifact token for mana, yielding an extra bonus mana with each activation. This combination lets you easily cycle the token's ability to generate an infinite supply of colorless mana.
