The only stats that seem to work as stated in the tutorial are power and defense. Also, the amount of damage the opponents do seems to be based on YOUR power not their own...this is just plain stupid.

why take away the option to see which blocks are removed? "as you become a game master you don't need this anymore." so??? who cares if i'm an expert at this game, give me back my options!
Need to revamp the "super stone". It's totally useless, even in combos (doesn't count as anything itself so you get less return from it than other stones...)
