Wouldn't be more practical to have the black info box (the one with HP,Max HP, Atk, Max Atk, position in field, turns of freeze/delay, passive skills) appear right when you hover the card, under the card image?
I know it's not always used, but i feel it would be better to have it available without wait when needed.
I also think that those values are getting more important as new cards come into the game.
If you feel this would confuse newbies, maybe it could be switched in setting:
infobox [instant | delayed]
