and everything under the sun is in tune
So according to the rules when the card comes into play it is cursed and thus the power and text are blank. As long as it stays cursed it is blank. But once it comes uncrused then the effect comes into play as long as it remains uncrused, Right?
Second, The card says that the opponent cannot claim supremacy no matter how much power he or she has in this column. But do you automatically get supremacy or do you still have to have the higher power to gain supremacy?
I think if you automatically got supremacy the card would have just said that—"You have supremacy in this column even if your opponent's cards have a greater total." Also, if it was the case that you automatically won supremacy, they probably wouldn't have only given it two curse counters if the "12" building has three, since it would obviously be much more valuable than the "12" building.
