Poke Ball
There are quite a few Item cards that feel necessary for specific kinds of decks or situations, but some will work just about anywhere. A fantastic example of this is Poké Ball, which adds one random Basic Pokémon from your deck to your hand.
This card doesn’t have any downsides. The only bad use for it is if it’s played late enough into a game when you no longer have anything to properly target. Things might change as new cards are added in future expansions, but it’s currently the kind of card that belongs in every deck.
