the lunar dance attack says 'you may discard 2 energy attached to cresselia. if you do, remove all damage counters from 1 of your benched pokemon'.
now sat i had a holon castform and a grass energy attached to cresselia, would i have to discard just the castform or would i have to discard castform and a second energy card to enact the effect of the attack?
