uMM, For these matchups:
Metanite- This is really bad...When gardy D ex comes, it's an autowin.
Ludi- This is way to easy. They can't one hit KO you with metal energies and their full bench makes black magic REALLY magical.
Typhlosion- Starmie is Awesome vs this. A strenght charm as a surprise and u KO the annoying Thyplo. Hard match though. Jirachi ALSO helps.
Mewtric- You pretty Much loose. Manectric ex resists you so you are busted. However, Gardy D ex will help this a LOT!

And i was testing this thing and it always come to the same thing. I have a big lead at start with Jirachi/Holon engine. I get a gardevoir and a starmie/Porygon2 on T2-T3 every game. But the problem is, I have to get Jirachi off the active slot. I currently play 2 switching cards (switch and a warp point), but it doesn't do enough.
At start, A shield tank Gardevoir with some metals can completely immobilize some decks, but at the end, when opponent's engine will start rolling and you will be hit 100 damage a turn, you cant do much. And they always keep their bench small so black magic's power drops dramaticly. You just don't have a good attacker late game.
Porygon2, Starmie, Jirachi DX in late game are completely useless. You only use them in early game and they can be targets for Cursed Stone/Something else. It becomes really hard for Gardevoir to win the game itself. Gardy D ex will do a lot, but another attacker is prob. Needed.
Hmm...Any help?
