Consider Flames of the Firebrand as a good way to clear opponent's early board.
Do you like Temporal Mastery ? I found it to be fairly mediocre when I've used it.
Flames of the Firebrand sounds interesting, I'll test it. And Temporal Mastery does a lot of work in this deck- it accelerates you into the late-game, the instant speed cantrips give you twice as much chance to miracle it, you can Reverberate it when you do miracle it, it gives you tons of value with your planeswalkers in play, and hard-casting it comes up surprisingly often. I've even had a few games where I've hard-casted it with both a Reverberate and a Chandra -2, fun times. Thanks for the suggestions.
Love the name! +1 just on that! Otherwise, a very interesting deck indeed.
