orbtran should be added as a lead, because he's an anti-lead for machamp
raikou (extremespeed) is also a great antilead, thunderbolt really hurts
though he should use hp ice and aura sphere as moves.
Tyranitar leads usually have the lum berry as item, sometimes I even face scarftar with sr (which is quite good, really)
ipl used blissey as a lead, though she has really a bad matchup.
There is also a rare gyarados lead who has great matchup against heatran, metagross and some azelf, which is good if you want momentum (you can add a shucatran with great sinergy to setup sr later)
Gone for good
