I was saying boo-urns
1) Cards placed on your Character by Firestorm do not resolve on each of your turns. Only when you actually play Firestorm. So, in your example, you would use the Bizarro Power's Attack each turn you play Firestorm.
2) You get the Weakness when you play/resolve Bizarro Power's text. So, you would get it as soon as you play Firestorm.
AHHH -- that makes complete sense (couldn't figure out the last line in the rulebook and the card didn't make it sound like it only resolves when Firestorm is played [risky card, but could see the crazy potential]
How about Firestorm Matrix with an attack card -- that cards becomes an 'ongoing' (obviously not Biazarro Power, but what about Catwoman). Also if I can attack, when should I? Beginning of the turn or when I want to resolve it? [or did I botch that card text as well]
