I agree that those three would be on my chopping block. Personally I'd keep Rag, especially since he's running Varian.
I know Maidens/Blocks are integral, but I don't normally see control warrior running 2 of each. IIRC my current control setup had two Blocks and one Maiden. Seems like a bit of overkill especially with Trueheart, just my opinion.
Actually I just checked Hearthpwn and this control variant does run 2 of each, whereas my setup was more like this. Neither updated for TGT yet. I would still personally recommend taking one Shieldmaiden out if you're running Justicar. Seems a bit top heavy. Also you wouldn't want to increase the chance to pull a Maiden out with Varian.
Well I guess you could call him a value card. He is still somewhat situational though. The number of times I've played him with low cost shit in my hand
I considered mentioning MCT but I don't think it's such a great tech card for control warrior unless the meta is gets insane. Which it might!
