You did just fine, don't worry about it, those decks build themselves. Although honestly, you probably want to go -3 bonewall, -3 plague, +6 SoSa, if you have them. Also if you do that -2 freeze and either +2 Mummy, +2 Bone Dragon, or +1 Bone dragon +1 Elite mummy. Or +1 Bone dragon +1 pillar. Depends on the quanta balance you'd have to test, and staying unupped.
