You might want to add more then two Sphinx main deck or a Pearl Lack Ancient. Sometime, you will have to let your sphinx die if you don't want to discard all your hand. Also, having a faster win condition might help to not draw match because you take too much time to kill your opponent.Anyway, if it plays well, keep it like that.

Hi! You might want to add some Obelisk of Urd since you play soldier creatures. You can cast it as early as turn 3! Also, with 18 lands, you might want to stay away from Iroas. Most of the time it will be a dead card in your hand!
