You can use as many Pokémon Tool cards as you want per turn, but you can only use one Tool card per Pokémon. So if you attach a Rocky Helmet on a certain Pokémon, you can’t stack another card, like another Rocky Helmet or a Lum Berry on top of it. Once your Pokémon loses HP and is sent to the discard pile, so too will the Tool card.

Good news! You can finally trade cards with friends in Pokémon TCG Pocket. Bad news! It sucks. It feels even more limited and backwards than when it was originally teased, and fans are in full revolt over the long-anticipated feature’s completely bungled rollout.
