TC doesn't mean "do well at getting half his HP taken away by Stealth Rock and then suck anyway"".
I use Charizard at the start(Before stealth rock) and use Sky Drop to ultimately make a double battle into a single battle every other turn in the download tournies
That's not standard OU though.
Have not played in ages. I assume a general support hold thier own rather than building a team around them, I used to sweep with MixedDDLapras for fun before, does not mean I can add him onto most teams.
Uxie is fantastic for setting up sweeps with Dual Screens and Memento. Gread lead and support that way. Has Metagross dropped yet? Using him as trick lead was handy. Agility Zapdos can really be great for momentum sweeping. Agility and start dropping the hammer of God on the team until Tyranitar or similar comes out, baton pass to Metagross/Terrakion and keep momentum and finish the sweep.
