Sucker Punch / Pursuit
Taunt the CM attempts, and if he thinks he can actually stay in and beat you, Sucker Punch it. If it tries to escape, Pursuit it.
EDIT: And a better counter for Weezing would be Heatran. Honestly, it resists two of his moves which would be going after Sceptile and it could easily OHKO with Overheat.
Well, this set's pretty dumb but..
Guts Max HP and Attack
Taunt blocks your Taunt whilst Guts takes Wow. SD while Pursuit/Sucker Punch does little or no damage.
