I do plan on doing at least one other uncommon, the Savage Land T-Rex. Was brainstorming them a bit today.
Also there is the He-Man T-Rex that would be uncommon as well.
I think it should all play fairly well. Old One Eye leads the group forward and charges in and takes a beating, follow that immediately with B&C&T&R, and once two or three of them fall, Golgotha and the Cursed roll in for clean-up.
Their end game may still end up being weak but they should really wreak some havoc in the meantime.
