You really don't want to draw it that much, and since you're playing 4 Knights, you already have things in your hand you may not be able to play. I would cut 1 fireblast for a horizon canopy. Since you're running knight you should run at least 1, and the extra help against mana denial is very useful.
Also, what is the justification for pyrostatic pillar in the board? I feel like you could get more useful things, especially since it hurts you so much.
