Some card explanations:
Dragonmaw Scorcher is here for the Odd Pally/Token Matchup. Your early game isn't great, but the upgraded Hero Power with Tar Creeper and Stonehill Defender can help stem some of the bleeding. The hoper is that you kill 4+ Silver Hand Recruits with Scorcher.
Crystallizer is the spiciest thing you've seen since your mom's curry. Turn 1 Crystallizer into Turn 2 Hero power makes it so that your Hero Power isn't useless early. Crystallizer sounds a lot better if you phrase it as a "1 mana 1/3 that gains 4 armor."
