Dark Rebirth (Dark Sylveon/Gardy)

Have you ever wanted to play Gardevoir but BAD? (And funny)

This deck relies on Gardevoir as an engine to power up Sylveon, which can mess with your opponent's hand with its Tricky Ribbon attack and potentially force them to top deck for resources. In the early game you should focus on taking KOs with Zacian and Gardevoir, going into Sylveon once your opponent has taken a few prizes and Iono can devastate their hand.

Though Sylveon doesn't have great HP, Ribbon Badge allows it to become a single prizer

Though Sylveon doesn't have great HP, Ribbon Badge allows it to become a single prizer which somewhat mitigates this. Even with its lower HP it avoids KOs from Cramorant after taking 60 damage from Psychic Embrace, or Sableye after 40 damage + manual attachment. Spiritomb shuts down Genesect V, completely preventing draw in DTE Mew decks and forcing the opponent to waste their energy in Fusion Strike Energy decks. The rest of the list is pretty generic Gardevoir stuff.

You could potentially run Crushing Hammer for more disruption, but I couldn't find room for it. If you're struggling vs Path most Gardy decks run Worker which can replace Avery, though once you get the hand lock going the chances of your opponent finding Path and it being useful in the situation become slim. Other than that feel free to make suggestions, this is the first time I've tried to make a somewhat meta deck since, like, the Sun and Moon era lol.
