Ampharos as a tech isn't bad, but I thought of Banette, and I think it will die just as quick as shedinja, which I don't want. By the way, here are some pokemon I have thought of so far:
1-1 Yanmega
2-2 Bronzong
1-1-1 Empoleon (Duel Splash can work late game).
1 Deoxys Normal Forme (A Good substitute for Azelf X)
1-1 Banette
1 Spiritomb (A little worried if he's my starter)
1-1-1 Victrebeel (For Special Conditions, and I get to choose).
Those are just the damaging techs, not the card support, etc. techs.
