yes the one that have even damageum ur talking bout SF #1 dusk right?
I dont have that dusknoir but thats a very good idea i try to pick one upAzelf Lv. X is pretty much a necessity, or else you run into problems in a mirror match when the opponent is using Azelf Lv. X and you are not.
Nidoqueen is a good tech, but I like the DP Dusknoir better. The ability to shuffle in a Benched Pokemon and then force your opponent to get it back out while they are under a Power Lock can win you some games.
Mewtwo LvX: Auto-win against all non-Dialga SP decks and buys time against Shuppet Donk.
