Vader you took the words right out of my mouth. I see CaP1 having:
A Great Defensive Typing coupled with adequate defenses allowing it to repeatedly come in and cause defensive momentum.
An array of stat-up moves along with average offenses to promote offensive momentum, causing the opponent to have to rethink their strategy.
Abysmal speed to elevate the use of U-Turn/Volt Change(Hello Scizor) and access to MH to allow the disruption of enemy momentum.
I can see the player sending out CaP1 to threaten the opponent out(Momentum gained). The opponent then assumes CaP1 is going to for example try Swords Dancing so they send in Skarm but then CaP1 uses Nasty Plot cause the opponent to again rethink(more momentum gained). If they respond with a sweeper CaP1 can utilize MH Thunderwave or another useful move. Granted all of that in one package seems rather OP but these were merely examples.
