How come the upped version makes it so much better? it gains 1 atk, 3hp, and it's ability is 50% more useful. Also, what exactly is a Pryntil? A quick google search didn't reveal anything, though I imagine that it's probably something like a harpy or mermaid. Why does charm cost ?
in the calculate maybe the skill should have vale 2, and the card shlud cost 2
Why to a minimum of 0, can't you just keep going?
Maybe the Art Curator could help a little more with this than I can, but is that art temporary?
