Ich-Tekik, Salvage Splicer + Arcbound Reclaimer + Lion's Eye Diamond + Crystal Skull, Isu Spyglass

Ich-Tekik, Salvage Splicer

Arcbound Reclaimer

Lion's Eye Diamond

Crystal Skull, Isu Spyglass

How it works

1. Activate Lion's Eye Diamond by discarding your hand and sacrificing it.
2. Ich-Tekik's second ability triggers, putting a +1/+1 counter on it and each Golem you control.
3. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Lion's Eye Diamond from your graveyard onto the top of your library.
4. Cast Lion's Eye Diamond from the top of your library by paying 0.
5. Repeat.

This ingenious loop is powered by Lion's Eye Diamond, which sacrifices itself for three mana of any one color while simultaneously feeding its own recursion. Crystal Skull, Isu Spyglass plays a vital role by letting you look at the top of your library and casting that very same Lion's Eye Diamond right back off the top. Meanwhile, Arcbound Reclaimer acts as the engine's recycling center, using one of its own +1/+1 counters to place the sacrificed artifact back on top of your library. Finally, Ich-Tekik, Salvage Splicer watches the continuous sacrifices hit the graveyard, growing larger alongside your Golems with every single iteration.
