Well, it's an anti-meta deck that uses Oricorio to win most matchups against ex decks, and Leafeon as an answer to Lycanroc/Rampardos, or just fight in general. It has a good matchup against Darkrai/Giratina thanks to Shaymin. Jolteon is kind of a meme and can be replaced with another Shaymin or any good supporter.

Unfort, this deck isn't perfect. One of the most annoying matchups — and it's getting more and more popular — is Greninja/Snorlax and Giratina. This deck really struggles against the Greninja + Cyrus bullshit, so well, just hope for the best :V
