Allright so this is a prototype designed to use Tamiyo, Field Researcher's ult to cast Emrakul, the Aeons Torn or Emrakul, the Promised End for free, as early as turn 4.
Nahiri, the Harbinger is also here because her ult can also bring Emmy out to play, sort of a Psuedo-redundancy thing
As with most planeswalker focused decks, Doubling Season is the star of the show as it allows either Walker to immediately ult, Nahiri getting Emmy out to annihilate their board and give you a free turn, or Tamiyo Drawing cards and letting you cast them for free
So Priority is to be able to cast Doubling Season, and Nahiri or Tamiyo as soon as possible, with a worst case Backup Plan of Hard Casting the Titans which brings us to the manaramp suite of Birds of Paradise, Sylvan Caryatid and Noble Heirarch.
So ideally it goes:
Turn 1 Land, Birds/Hierarch
Turn 2 Land, another Birds/Hierarch, Caryatid
Turn 3 Doubling Season
Turn 4 Either Walker, Bring In Emrakul, the Aeon's Thorn
Turn 5 Profit
Obviously there are potential problems, especially with failing to draw into either Walker or Especially The Doubling Season, but I've built in as much redundancy as I know of. I would Really Appreciate any help I could get with Redundancy for Doubling season, as it's the weakest link in the chain, also I would like to hear some opinions as to whether There is too much ramp, as the goal is to Use Tamiyo's Ult which would then make the ramp cards Irrelevant, Do I need to have Fewer Emrakuls and more other bombs, after all, Legendary Rule is a thing, Please Comment, and if you like the idea of a turn 4 Emrakul, please Upvote, and if you hate the idea of a turn 4 Emrakul, Please Upvote
Thanks, See y'all around-JLC
