Nope. It's Lee Sin.
I do the invasion route in 5 v 5. Starting with a Longsword + Pot (requires defensive masteries). Starting at enemy wraiths (with team assistance) -> wolves -> wraiths -> mini-golem | Back -> Grab Blue/Pass it to Mid -> Look for gank opportunities.
If they have a good AoE damage jungler like Amumu or Nocturne that will want to take Wraiths asap, I just go Cloth + 5pots, starting at my wolves and only killing the large one. Then take blue and proceeding down the normal path.
Rushing Wriggles, grabbing Merc Threads (or Tabi, if no fear from enemy CC and the have more than one autoattacking demon). From there I go Phage + Giant's Belt and move straight into Atma's without upgrading into Frozen Mallet. I'll only upgrade to that when I need the invent room.
I don't build Trinity or Mogs, even if I'm snowballing off of enemy stupidity. If I am snowballing, I get a Gunblade. It seems like an odd choice, but the spellvamp with all his skills, on top of the added lifesteal lets you Q into a 1 v 2, and dash out with a free kill midgame.
Final build tends to be:
Wriggle's, Merc Threads, Mallet, Atma's, Force of Nature, Gunblade, [Sell Wriggle's], Sunfire Cape/Situational
3 v 3, starting item is basically immediate counterbuilding or a Dorian Blade for a lvl 1 gank. Same build, more or less. But I don't take Smite unless my other two allies are completely imcappable of burst to help secure the Dragon.
