If my opponent has Goodra with the "Slimy Room" Ability in the Active Spot, do I still have to flip a coin to attach an Energy to one of my Pokemon that already has a Fusion Strike Energy card attached to it?
Yes you still have to flip a coin, because the Slimy Room Ability is acting on you the player not on a specific Pokemon; and Fusion Strike Energy's effect applies to the Pokemon it is attached to, therefore it does not block Slimy Room's effect.

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.

While Goodra’s “Slimy Room” Ability is active, if I try to attach an Energy card but flip tails and have to discard my energy instead of attaching, can I try again?

If I have multiple Toxtricity with the "Maximum Downer" Ability in play, will my opponent's VMAX Pokemon have -30 HP for each one?
There is no restriction about multiple Maximum Downers being in effect; in other words, yes it stacks.

Does Chandelure VMAX's "Cursed Shimmer" Ability prevent Maractus' "Ditch and Shake" attack from discarding any number of Pokemon Tool cards?
No, Cursed Shimmer only prevents the opponent from playing Pokemon Tool cards from their hand; that is not the same thing as discarding Pokemon Tool cards for Ditch and Shake.

If I have Milotic with the "Dew Guard" Ability in play and my opponent plays Avery, do I have to discard Pokemon from my bench until I have 3 or not?
Milotic's Dew Guard prevents all effects of your opponent's Supporters that are done to you, so you would not discard any Pokemon from your bench for the second part of Avery.

If I use Zoroark's "Phantom Transformation" Ability to put a Stage 1 Pokemon from my discard pile in its place, may I evolve it into a Stage 2 Pokemon right away?
The Stage 1 Pokemon you're putting in play is completely new; nothing carries over, and you can't evolve a Stage 1 that came into play that turn.
