I really like the fresh idea and really want to break the djinn, but having to wait for two more combo pieces after you oathed up your fat seems sub-optimal to oathing up an angel or tyrant and ending the game right there. Is this the Danger of Playing Cool Things?
Anyway, I really like the synergy anger would have in this deck. Except of course, it would have to change your manabase around.
It's usually pretty easy to get those combo pieces out fast, like I said, it usually goes off around turns 3 through 6. I'll admit, Tyrant is better, but this can still win games and be competitive (probably not Tier 1) and also be a lot of fun to play.
