This Pokémon can use the attacks of any Basic Pokémon in your discard pile, except for Pokémon with a Rule Box (Pokémon V, Pokémon-GX, etc. have Rule Boxes). (You still need the necessary Energy to use each attack.)
I ordered 3 tins, and they made sure to send 3 different designs, thanks! Sadly 1 tin did arrive with a dent in it. It also took almost a week to be shipped.
