Definitely stole the scizor idea from another player on Live, but here's my spin on it (the list I use on Live)
Jirachi actually comes in very clutch randomly, Kleavor is for matchups like Miraidon and Arceus VStar, Echo horn just got a whole lot better since Squawkabilly ex is seeing a bunch of play, Vitality bands and Studios fix a lot of math, making it easier to hit the magic 220 damage #.
4 Boss is crucial, trust me you'll need them.
Definitely better to have 4 of the Scyther from Obsidian flames, but I only have 2 so... yeah. Fix that if you can.
Fun and dynamic with many options on every turn.
Good luck all!
