Chaos Control, by far. Even the Trainer Kits look like gods compared to Chaos Control.
It has only 2 useful Pokemon: Tyranitar (which is terribly difficult to use: you also need to get Pupitar without any searching except 2 flippy Poke Balls, and you need to get 2 out of 3 Darkness Energies because Tail Crush is horrible. During my quest to get 12 wins, I got Pupitar and Tyranitar together only ONCE, and I had to duel 30+ times thanks to all the losses), and Lucario which is on the low end of usefulness.
The rest? Mismagius deals a LOLworthy amount of damage, the 2x Metang can do a little bit of damage but it really shows they need to evolve further, aaaannnd... oh wait, that's all: for the rest you're stuck with cards like Zubat. Good luck!
At least its counterpart, Steel Sentinel, has some more ways to win: it has 6 basics that can do a decent job without evolving (Onix and Tauros, which are about as good as Metang thanks to their colorless-ness and being basic), Steelix is way easier to use thanks to being stage 1, and Roserade can really dish out the hurt by sending out confusion while it's slowly powered up on the bench.
