If you protect the Permafrost Shield, your Bone Walls and Wings are all dead cards. It's probably not all that great of an idea to run 'permanent' shields like Permafrost in a deck that has 5 shields.
Needs more PC. You only have 2 cards in essentially a 36-card deck, and to make things worse, one of them isn't Pulverizer.
I question the use of Shards of Divinity. I question it very much.
I question the use of Precognitions. Replace them with 2-3 Hourglasses.
Why Eternity? You won't have enough quanta to use it much and you already have Pulverizer.
I'm not very good with quanta balance, but this deck is bigger and uses more quanta than CCYB while having fewer pillars than it. That can't be a good thing.
Maybe I should explain why I have what I have.
1.
Precogs instead of hourglasses. The precogs serve a dual purpose, They give you some extra cards at the begining for cheap and Let you know what the opponent is packing. They also dont drain your time quanta like HG do so you can use eternity much more. This is deck is meant for the arena and possibly AI4. where what the opponent has can be completely random.
2.
permafrost versus Bonewall versus wings. I have them all because they serve very different purposes. One blocks 2 damage and has a chance to freeze, one blocks each individual attack, and one blocks some damage from non flying creatures. Many times I will throw out the wings or the permafrost early game, till i get a quinted oty and a firestorm, then switch to bonewall and start smashing creatures. and I dont have many good sources of healing, so just leaving the protected permafrost will eventually get you killed. especially versus something like a farenheight. (also, I often use a set of wings to draw out permanent control if the opponent is sitting on 1 or 2 deflags.)
3.
PC?. I just havent found that I need it that much. Many Arena decks either protect their permanents, or they simply dont play that many. The PC is mostly for very late game if the have something like dimensional shield or something, and generally you will have a mutant by that time that can destroy it anyway with steal or destroy, or endow+pulveriszer.
4.
Shard of divinity. Its basically meant to help you survive an initial rush, an etra 16 or 32 health can mean a lot when you are trying to set up some control. thats basically the thought process, + 6 from shard of graditude doesnt really help this deck, and it doesnt have the quanta for something like a mirracle. once you have control of their creatures and a bonewall set up, 2 Sancs are generally more than enough to stay allive.
I know it looks kindof strange, but it has been not bad while i have been playing it in the arena silver. Please give it a try and then give me feedback.
