If Path to the Peak is in play and I play four Missing Clover to take a Jirachi {*} from my face down prizes, will I be able to use its "Wish Upon a Star" Ability?
Yes, you may. You are taking a Prize Card and the Ability is activated before it is in the hand or in play, so Path to the Peak does not stop it.
