First of all,this is a team,not a lead.And I saw this team on a website.Apparently,it reached a streak of 188!
This is the team and how you should use it:
Shuckle (Bright Powder)
Garchomp (Yache Berry)
Start with Shuckle
Encore the first move
If a water move swith in vaporeon
use HP electric, kill it
if steel or poison, switch in garchomp
earthquake to kill
I got this one from Yahoo Answers
Hope I helped!
