You're incorrect. The question's already been brought up, and answered, in the Compendium. The "only provides 1 Energy at a time" primarily refers to purposes of attack cost; e.g. an attack that costs {L}{M} cannot be paid with only a single Rainbow Energy.your roserade/ rainbow question. they are all wrong. if you read the card. it provides ALL types of energy, but can only provide 1 at a time. it says that on every card that has potential for multiple types. so you would have to choose.
No.thunderus > all
that NEVER happened.if i can remember right, just a few months ago donphan was destroying mewtwo. 1 energy for 60 damage. and he was damage his own bench.
