So... someone told me that double rainbow energy provides 2 different energies one time, is it right or not? Or is provide 1 type of energy but 2 energies? tell me plz!!!
Both the energy types it provides can be different (for example the other one can be fire and the other one can be metal ect.). Remember. It's EVERYTHING at the same time.
You can't really choose what it is. It is everything at the same time. If an attack needs it to be fire, it will provide fire. But at the same time it's fighting, water, grass and so on.
I'll give an example.
Your pokemon has an attack that sais to discard all metal energys attached to the pokemon. You have Double Rainbow attached. You can't choose the Double Rainbow to be only fire (so it wouldn't get discarded), it is still metal at the same time, and you have to discard it to use the attack.
There. Hope that helps. It's all energy types at the same time
