-Unupped SoSe is just because of certain pvp events, I haven't upped most of my rares.
-Blessing is a hit and miss, I'll give you that.
-Lightning Storm I regretted not having, more than having.
-The Warden is in there for the Blessing synergy alongside Otyugh (I prefer killing CC), if I took one out, I'd take both.
-I've never found myself wanting EH, Fate Egg and SoSe provide most the damage in this deck.
-SN doesn't work well in this deck. I've tried.
-The extra pillars are mostly there for SoSe cards.
-I always win against mono-air. But then again, I don't often run into SoFr packed decks in Bronze...
-I forgot to mention this deck doesn't do well against Bone Wall Decks. Drawback of relying on CC.
All your points are valid, but I threw Tried-&-True logic out the window to build this deck, and it seems to work great.
If you can modify it to have a higher win rate than 94%, go for it. I have a feeling it's only 1 or 2 cards away from a 96% or 98% anyway.
