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 used to run pyuku in ubers as a xern counter (while i was a noob) but it's been working pretty pog in ou as well
a toxic stall is also an option, a spdef set with toxic soak recover +move of your choice works fine.
Yeah kart should def have cb>lo but the rest of the corrected team looks solid. IMO electric sd lucha is one of the most fun sets to do in ou and fits very well in most ho teams.
