Slime Mold Colony - Pokémon Rulings Compendium

How does Skater's Park work if I have Toedscruel with the "Slime Mold Colony" Ability active?: Slime Mold Colony only affects your opponent's discard pile. However, while Skater's Park is in play, the basic Energy that would be discarded when your opponent retreats never makes it to the discard pile, so those cards would go into their hand.

How does PokeStop work if I have Toedscruel with the "Slime Mold Colony" Ability active?: Slime Mold Colony only affects your opponent's discard pile and their Abilities or Trainer cards (it doesn't do anything to its owner), so the behavior of the PokeStop stadium depends on which player owns it. For example, if I have Toedscruel and my opponent uses their own PokeStop, they would be able to discard 3 cards from the top of their deck but they wouldn't be able to put any of those discarded Item cards into their hand. However, if I have Toedscruel and my opponent uses *my* PokeStop, it works normally because Slime Mold Colony does not affect *my* PokeStop.

Can I play Superior Energy Retrieval while my opponent has Toedscruel with the "Slime Mold Colony" Ability active?: If you do that you would discard two cards for Superior Energy Retrieval, but you would not get to retrieve any energy cards from your discard pile.
