While Goodra's "Slimy Room" Ability is active, if I use an Ability or card effect like Swampert's "Muddy Maker" Ability to attach an Energy card from my hand but flip tails, can I use that ability or effect when I try again with another energy?
No. The Ability has been used and the energy is discarded even though your regular Energy attachment for the turn has not been used up.
