The most recent Tyranitar's Ability, Roar of Anger, states the following: "You may use this Ability when you play this card from your hand to evolve 1 of your Pokemon. Attach as many [D] Energy cards from your discard pile to this Pokemon as Prize cards your opponent has taken." Suppose a player has been using Palkia & Dialga LEGEND's Time Control attack, which includes the following effect: "Add the top 2 cards of your opponent's deck to his or her Prize cards." Which player (if not both players) is responsible for tracking the game state of Prize cards? If a dispute between two players on how many Prize cards have been drawn arises, how should a judge handle the situation?
