Persian

Starting this list is Persian, which might initially sound like a tough sell. Not only does its Shadow Claw attack require two Colorless energy and only deal 40 damage, but it’s a stage-one Pokémon and will require you to evolve a Meowth just to bring it out. What makes it worth it, however, is the Shadow Claw’s ability. You’ll flip a coin with every attack, with heads forcing your opponent to discard a random card from their hand. This effect can greatly disrupt any player’s plans when you remember every deck is only 20 cards.
Additionally, Meowth isn’t a bad card itself. Its Payday attack might deal a measly 10 damage, but its effect lets you draw a card with each attack. Both this ability and the one from its evolution can be pretty handy.
