This looks like a pretty solid deck, I can't think of any match-ups that would be a nightmare. Though I'm curious, you have a brimaz in your maybe-board and double white seems pretty hard for your mana-base. If you were going to include him, would you change your mana-base?I'm new on this site, and a pretty casual player, so take my opinions with a grain of salt.

Hahaha, I just copied this from my Abzan Deck, and I forgot to update the Maybeboard. Thank you for the heads up. The only thing I am wondering is if I should lose some removal spells for counter spells, and which counter spells? Perhaps keep both, and just have a 6-8 counter spells in my sideboard?
