How it works
Activate Dark Sphere by tapping and sacrificing it.
Ich-Tekik's second ability triggers, putting a +1/+1 counter on it and each Golem you control.
Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Dark Sphere from your graveyard onto the top of your library.
Cast Dark Sphere from the top of your library by paying 0.
Elsha's prowess ability triggers, giving it +1/+1 until end of turn.
Repeat.
This fascinating engine turns a humble zero-mana artifact into a recurring resource by looping it directly from the graveyard to the top of your library. When you sacrifice Dark Sphere, Ich-Tekik, Salvage Splicer notices the artifact hitting the graveyard and rewards you by growing itself and your Golems with +1/+1 counters. You can then spend one of those accumulated counters using Arcbound Reclaimer's ability to recycle Dark Sphere right back onto your library. From there, Elsha of the Infinite lets you cast Dark Sphere immediately off the top of your library with flash, feeding Elsha's prowess trigger for a massive temporary pump while setting you up to repeat the entire loop infinitely.
