Hey guys, I'm pretty new to magic and was wondering if I could get an appraisal on my new Standard? I had an Izzet before the rotation that worked pretty well https://deckbox.org/sets/781863 but now RtR is gone and Khans is in I built this https://deckbox.org/sets/792756 Can I get some feedback?

Personally for my taste, it's a little to over the place. I get what you are going for, but I would add in more ramp if you are going to use those big creatures (you have a really high mana curve) if you are going to use chasm skulker add more draw into the deck and maybe remove some of the big fatty creates, or make it a little more consistent add in 1 or 2 more kiora and remove the xenagos and ancient silver backs, and put in arbor colossus as well.

I agree with you about the mana curve, it's not something I could get away from, and broke the budget getting the Rattleclaws, Surrak and Kiora (so damn expensive) so had to settle with cards I already own, that's why I included Market Festival. Thanks for the advice I'll definitely look into it
