Welcome back from Mars. Six more similar cards have checklists of all 150 Pokemon. Only 22 Pokemon are actually provided as cards in this set. These are indicated in red on the checklist and the fact is noted prominently. The rulebook explains how to use the Pokemon power cards to play Pokemon contests.
Contest procedure is appropriately simple.
When you attack, you roll the die. If the number showing is one listed on your power card, the attack succeeds. Each attack has a number of hits shown. The target gets than number of hit tokens. Some cards also instruct you to flip a Pokemon coin.
