maximum amount of energy question

[Sooner811]

Is there a maximum number of energy cards you can attach to a pokemon?

I ask because my Blastoise has an attack that does 60 damage plus 10 extra damage for every water type energy attached to him. Can i attach 10 water energy to him and do 160 damage each time?

no energy limit. its only limited to how many u can fit into ur deck
