Key cards: Cabal Therapy, Duress, Ad Nauseum, Chain of Vapor/Void Snare, Burning Wish Cards to consider removing: Jace, the Mind Sculptor, Force of Will, Pact of Negation, Emrakul, the Aeons Torn Cards to consider adding: Trickbind, Flusterstorm, Leyline of Sanctity, Ravenous Trap, Noxious Revival, Surgical Extraction, Echoing Truth Burn: Leyline of Sanctity is king here, but Eidolon of the Great Revel is the equalizer
This would line up with the three new cards mentioned in the teaser
With four different keywords to make the card extremely hard to deal with, Atraxa, Grand Unifier cements its place in the expansion quite well, which is why it's the highest-valued card under 100 dollars
If you do, create a token thats a copy of that creature
Its not hyperbole to say the Valley has everything a trading or sports card fan could want
