Everflowing Chalice (4 counters) + Voltaic key + Rings = Infinite colorless

Deserted Temple + Scorched Ruins + Rins = Infinite colorless

Expedition Map - Help you find temple, eye of ugin (to find kozilek to refill hand or other eldrazi, also, ramp), or any utility land. It also helps ensure you don't miss a land drop early game.

Field of the Dead - Zombies eat brains for breakfast. Yummy

Mystic forge + Sensei's divining top + artifact cost reducer Cloud Key/Semblance Anvil/Ugin Ineffable = Draw your entire deck. Also note, top + rings w/ basalt = draw your entire deck

Ugin, the Spirit Dragon - Wipe

Blinkmoth Urn - Ramp

Blinkmoth Well - Politics, tap blinkmoth urn, or Winter Orb.

Mycosynth Lattice = Fun shenanigans, especially with urn. Combine with an Karn, the Great Creator for a hard lock. Karn could take the place of liquid metal tongue perhaps?

Metalworker + rings + voltaic key = Infinite colorless

Grim Monolith + forsaken monument + rings = Infinite colorless

Chromatic Orrery + rings + voltaic key = Infinite colorless

Most if not all of the cards suggested for combo are also relevant without it, ensuring little to no dead cards. Let me know what you think, looking forward to your response.

Profet93 Hi! This deck is already over the budget but I'm still planning to get at least a gold-bordered Grim Monolith because my Basalt always gets demolished faster than the speed of light. Expedition Map, Chromatic Orrery and Ugin, the Spirit Dragon are definitely worth spending, though! Also, I didn't realize the infinite combo potential of 4-kicked Chalice. I'll add it in the description, thanks!

As for the zombies and artifact creatures, I'm trying to limit it to Soul of New Phyrexia and the 2 land fetch bots for now. I really love the idea of huge Eldrazi creatures trying to win as a theme (no pun intended).

Thank you very much for taking time in writing this. This is very informative and will really help me improve the deck!

I didn't see any mention of budget in the description, just wanted to provide optimal synergy. I'm glad some suggestions helped. Looking forward to your update and how your games play out.
