During Sudden Death, I can use Counter Catcher (always)

During Sudden Death, I can always use a Counter Catcher, but since I always have 1 Prize card remaining, and my opponent also has 1 Prize card remaining, I shouldn't be able to use that.

In the E regulation standard format, Counter Catcher must always be unusable. However, the cards that were able to add Prize cards to the opponent are available in the Expanded format: CIN Nihilego-GX, SM68/UPR Xurkitree-GX, and UNM Naganadel-GX.
