I've been playing variations of this on-and-off since Kaladesh came out, with around a 60% win rate. It's pretty matchup-dependent, and there are certain cards like Gideon where you probably just lose if they resolve, but the early game is fine and the late game is one of the best in the format; few decks can beat TKS or Smasher backed up by countermagic.
