Help with w/e. I don't have a budget, really. I am centering the deck around Thrax, hence the things that give him hexproof/shroud/indestructible and flying/intimidation/fear. I currently feel like my deck is a little too one-sided and something like a hinder and bad card draw could ruin the game for me. I need suggestions on just about anything, I am wondering if my land choices were the best to go by as well.
