Also, I suppose you are playing Jin-Gitaxias, Core Auger, so you do have the ability to limit their hand, just not quite as fast, although speed is less of a concern in a petal-less build. I love your list, and will be playing it soon. I've got it put together with the sub-optimal mana-base, but -1 MisD and -1 Jace, +1 Izzet Charm and...I don't remember. Might be a Grave Titan.
From my phone. I do my best, dammit!
