Arcbound Reclaimer + Showdown of the Skalds + One with the Multiverse + Dark Sphere

Arcbound Reclaimer

Showdown of the Skalds

One with the Multiverse

Dark Sphere

How it works

1. Cast Dark Sphere 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 Dark Sphere by tapping and sacrificing it.
4. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Dark Sphere from your graveyard onto the top of your library.
5. Repeat.

This intricate loop lets you endlessly recur **Dark Sphere** by turning the counter-buffing power of **Showdown of the Skalds** and the library-snooping, top-deck casting abilities of **One with the Multiverse** into a self-sustaining engine. Because **One with the Multiverse** lets you cast spells right off the top of your library for free once a turn—and since **Dark Sphere** costs zero mana to begin with—you can continually deploy it and trigger **Showdown of the Skalds**'s second and third chapters to place fresh +1/+1 counters onto **Arcbound Reclaimer**. Those counters become the exact fuel **Arcbound Reclaimer** needs to fish **Dark Sphere** right back out of the graveyard and place it precisely where **One with the Multiverse** can cast it again, building up an endless storm count and infinite artifact triggers.
