First draft of an abzan flicker deck featuring Ephemerate, Charming Prince, and everyone's favourite rhino.
The basic idea is to drop walls early to accrue card advantage and buy time. You can then use your extensive removal and protection suite to control the game, rebuying spells (in particular, Ephemerate itself) as needed with Eternal Witness + Ephemerate/Charming Prince. Eventually, you drop a Siege Rhino and attack/flicker it until opponent is dead. Knight of Autumn provides extra removal or a solid backup beater as needed.
The sideboard is a mess and should probably not be used as is.
The maybeboard:
I had the idea of switching out the Wall of Blossoms for Stitcher's Suppliers, and adding the fourth Eternal Witness and some number of Witch's Cottage plus some swamps to help activate them. This would trade some card advantage for a greater amount of virtual card advantage, lowers the curve and allows for more turn one plays. Obvious downside is even more reliance on the graveyard for a deck which already abuses it, and also you're leaning more heavily on finding an Eternal Witness. Further, with Charming Prince's scry 2 on enter ability, we already have access to a powerful selection engine that doesn't die to rip.
Lone Rider is a potential 2 mana beater to throw in the side. Goyf is pretty suboptimal in this deck for obvious reasons, where Lone Rider is a pretty solid 2 mana beater who flips pretty easily on the back of Charming Prince, Knight of Autumn, or Kaya's Guile.
