Naya Enchantment Walkers (Standard)

The early turns are usually spent getting rid of small creatures with enchantment based removal/chump blockers. On games where herald of the pantheon survives, you can spend these turns pushing out tokens pretty quickly or ramping into more powerful enchantments such as starfield. Blight Herder allows you to remove the creatures from your enchantments' grasp so you can swing in/block to have them die purposefully to be brought back with starfield. The oaths also allow some pretty impressive stuff with the 3 planeswalkers (possibly nissa would be a good addition if focusing more on the token route) Gideon can emblem and survive first turn with OathOG, sarkhan can set up your super draws if thats what you need if you untap with him, chandra has more wiping potential or can survive the backlash of pesky manlands after small board wipe. A single copy of impact tremors helps get around creature board stalls by buying back the legendary Oath of Gideon every turn (possibly in multiples.) 3 damage to any creature every turn doesn't hurt either with oath of chandra and starfield.

SIDEBOARD
Bonds of mortality opens up killing indestructible planeswalkers or hexproof dragons while cantripping and maybe providing a small life boost from herald. If you are looking for a walker with starfield out, putting one out that got d commanded, milled, sac'd some other way could be useful.
Full 4 surges against mono red/atarka red as some of this decks removal may be too slow without herald of pantheon surviving.
Radiant flames can clean up some of the 3 toughness guys in rally that koz. return won't hit.
Outpost siege can be great against midrange or control on either mode depending if you have your looping OOG's going on or not. Kozileks return is much better than radiant flames against atarka in reponse to hasty swinging lethal.
Ulamogg for those long games where you can hit 10 mana. He's big, He's bad, He doesn't require waste mana.

Modification Options
Nissa, VoZ for more token fun possibly with one more impact tremors and a secure the wastes
Hallowed Moonlight in the sideboard might be necessary, but have not tested against 4c rally. Not sure if all the exiling is enough or not.
