Golden-Tail Trainer Marcy: I'd love to have this card in Standard for GW Enchantments, but alas

There might be some formats that change those rules, like Prerelease tournament that diverges from official rules such as: 40 cards in deck only 4 prizes no "only 4 Pokmon with the same name deck" rule I strongly recommend to play using the official rules at all times so you are not surprised when you attend a league or a tournament for the first time
