Arcbound Reclaimer + Showdown of the Skalds + Lotus Petal + One with the Multiverse

Arcbound Reclaimer

Showdown of the Skalds

Lotus Petal

One with the Multiverse

How it works

1. Cast Lotus Petal either from your hand or from the top of your library by paying 0
2. Showdown of the Skalds triggers, putting a +1/+1 counter on Arcbound Reclaimer.
3. Activate Lotus Petal by tapping and sacrificing it.
4. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Lotus Petal from your graveyard onto the top of your library.
5. Repeat.

This engine relies on One with the Multiverse to play Lotus Petal right off the top of your library for free, triggering Showdown of the Skalds to place a +1/+1 counter back onto Arcbound Reclaimer. You then sacrifice the Lotus Petal for mana and use Arcbound Reclaimer's activated ability—fueled by the counter you just received—to recycle the Lotus Petal straight back to the top of your library. Because One with the Multiverse lets you continually play that top card, this loop feeds endlessly into itself to generate infinite mana, artifact triggers, and storm count.
