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.
