If I already have four Fire Energy cards in my Discard Pile, can I use Superior Energy Retrieval to discard two Fire Energy cards from my hand and retrieve the other four from my Discard Pile?
Yes, you may retrieve the other four. The restriction is you cannot return any of the cards to your hand that you used to pay this card's cost.

How does the stadium card Frozen City interact when a player attaches Double Colorless Energy to a non-Team Plasma Pokemon?
You only place 2 damage counters because there was just one attachment, even though the attachment provided multiple energies.

If my opponent has no cards in their hand, and I only have 1 Colress in my hand, and neither player has any Benched Pokemon, am I allowed to play Colress or not?
Yes, you can. You would shuffle your "hand of zero cards" into your deck and draw nothing.

If my Active Pokemon is Snorlax with the "Block" Ability, what happens to my opponent's Active Pokemon if I play Escape Rope?
