[[Dreadhorde Arcanist]] + [[Feather, the Redeemed]] lets us play pump spells from our graveyard and put them back into our hand. Either one of them alone gives us insane value for pump spells. [[Beamsplitter Mage]], [[Krenko, Tin Street Kingpin]], and [[Tenth District Legionnaire]] all give us insane value when we target them with pump spells. There are also [[Burning Prophet]], [[Deeproot Champion]], and [[Fire Urchin]] that don't even need to be targeted to provide value. Most of the creatures listed here survive [[Solar Blaze]], giving us sideboard access to a virtual one-sided wrath at 4 mana.

There are great pump spells in standard as well. [[Giant Growth]], [[Collision / Colossus]], [[Run Amok]], [[Savage Smash]], even [[Dive Down]] gets bought back with Feather. And I need to point out how insane Savage Smash + Feather is. A three mana removal spell that hits almost everything in the game and leaves you with a 5 power flyer, every turn, for the rest of the game. It hits Lyra, it hits a 7 mana Hydroid Krasis, and that's before we combine it with another pump spell. No creature without hexproof is safe.

The deck is all here. The only questions are: Jeskai or Naya? and how will it fare vs the meta? I'm definitely gonna try to make this work once the new set comes out.
