Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I've got a few ones:
Roost vs. Roost (Highlight on Turn 18)
Machine vs. Nature (82 turns)
Skullgirls Team (proud of this one, but opponent forfeits...)
HGSS Red Team
And my favorite one:
KINGler

I got lucky that the Blaziken didn't swichted. But still, Kingler is now one of my favorites just because of this battle.
