Astelli Reclaimer + Lotus Bloom + Lion's Eye Diamond + Meticulous Excavation + Roaming Throne

Astelli Reclaimer

Lotus Bloom

Lion's Eye Diamond

Meticulous Excavation

Roaming Throne

How it works

1. Cast Astelli Reclaimer for its warp cost by paying 2.
2. When Astelli Reclaimer enters, it triggers twice, returning Lion's Eye Diamond and Lotus Bloom from your graveyard to the battlefield.
3. Activate Lion's Eye Diamond by sacrificing it and discarding your hand, adding .
4. Activate Lotus Bloom by tapping and sacrificing it, adding three mana of any color.
5. Activate Meticulous Excavation by paying 2, returning Astelli Raclaimer from the battlefield to your hand.
6. Repeat.

This elegant loop sets up a self-sustaining engine built around the clever cost-reduction and recursion of Astelli Reclaimer, which we cast for its warp cost to cleanly set its mana value at three. With Roaming Throne already naming the creature type to double our triggers, Astelli Reclaimer's entry pulls both Lotus Bloom and Lion's Eye Diamond straight back from the graveyard. Sacrificing those artifacts yields the necessary mana, while Meticulous Excavation neatly bounces Astelli Reclaimer back to our hand so the whole cycle can begin anew.
