Zacama Stax (EDH / Commander)

This deck is a Naya-pimp-your-mana deck focussed at Zacama, Primal Calamity.

Ramp up with spells like Three Visits, Skyshroud Claim, Nature´s Lore, Cultivate etc.
Fix Mana with Smothering Tithe, Birds of Paradise, Arcane Signet, Knotvine Mystic etc.
Try to get some Draw with e.g. Sylvan Library or Esper Sentinel.
Make sure to use Zacama´s ETB for maximum output, maybe combine with Mirari´s Wake, Nyxbloom Ancient or Mana Reflection. Reshape the Earth obviously provides you with a solid amount of all the mana you need.

Getting out Zirda, the Dawnwaker when having Zacama on board is game winning, for you can use the activated abilities for just one colored mana.
Furthermore try to win by abusing combat damage and direct damage, combined with Gisela, Blade of Goldnight, Finale of Glory, Stuffy Doll and Brash Taunter. Alternatively you can use huge dumb creatures like Shivan Devastator, for you are trying to get 30+ mana at end of game. I´m currently thinking of putting Finale of Devastation and Blightsteel Colossus into the deck for having more flexible win-cons.

Use Seedborn Muse and Wilderness Reclamation to boost up your mana during opponent´s turns.

Other cards like The Great Henge, Silverback Elder or Elder Gargaroth will help to stay in game while ramping up for Zacama, Primal Calamity. Also protect yourself and your cards by Heroic Intervention, Akroma´s Will or Dragonlord Dromoka, as well as prevent the incoming Zacama-Counterspell with Spellbreaker Behemoth or Prowling Serpopard. You can also stay flexible in opponent´s turns with spells like Guttural Response (great counter for Cyclonic Rift) or Boros Charm.
