hi. i had a couple questions about this game. i'm starting to like it now but what are the ranks of the card? here is normal rare special hero is that the order? can i upgrade a normal card to hero by leveling it up? also, i noticed there are multiple grades for each player, like howard will have a special, rare, and regular version. should i wait to level up only the hero version? lastly, when you are fielding, what does the blue glove icon button do on the bottom right?
