I already stated this in the general thread, but I'll put it here just to be sure that it gets fixed before this set is released: this card has a typo. Same one as [mwcard=MWSTX1CKJ02]Wizard's Tower[/mwcard]. Unique needs to be in black text, not gray.
Why is this important? Well, for a significant amount of time, I believed that Wizard's tower was restricted to one per deck (like epic), because unique was in gray text and I did not remember the definition. I am sure there are many players out there still under this illusion. Upholding conventions is important to help players understand the game.
