Tameshi, Reality Architect + Lotus Bloom + Copy Artifact + Ancient Den

Tameshi, Reality Architect

Lotus Bloom

Copy Artifact

Ancient Den

How it works

1. Activate Lotus Bloom by tapping and sacrificing it, adding .
2. Cast Copy Artifact by paying 1, having it enter the battlefield as a copy of Ancient Den.
3. Activate Copy Artifact by tapping it, adding .
4. Activate Tameshi's second ability by paying and returning Copy Artifact from the battlefield to your hand, returning Lotus Bloom from your graveyard to the battlefield.
5. Repeat.

This clever loop revolves around Tameshi, Reality Architect, using its ability to recur Lotus Bloom from your graveyard by bouncing a land to your hand. To keep the engine running, Copy Artifact steps in by entering the battlefield as a copy of Ancient Den, giving you the white mana source required to pay Tameshi's activation cost and bounce the copy back to your hand. As a wonderful bonus, every time Copy Artifact is returned to your hand, Tameshi's passive ability triggers to draw you a card, turning your infinite mana loop into an unstoppable draw engine.
