ADC Thresh chops away 60% of an enemy's health with his first strike, and his CC keeps people subdued long enough either way. It's actually quite good - I know someone who mains him and usually carries.

AP Varus is awesome, as it was already mentioned. Tanky AP Nasus does everything else as well as AD Nasus (with Lich Bane, his Q hits harder than that of a traditionally built Nasus), while turning Spirit Fire into an amazing poke. His ult is capped though. AP Udyr deals good damage with phoenix and Lich Bane, and his shield becomes ridiculous (he can effortlessly solo the baron!).

AP Gangplank is all the rage right now, so you probably know about him already.

I wouldn't consider those things troll builds, as they're situationally viable, but as this post seems to be more about unconventional builds in general, I think I should mention them...

Here's some more genuine troll builds:

Singed with 3 RoAs+Seraph's+Rabadon's. Great damage output and stupidly survivable, but only if your enemies are don't know about BotRK/Liandry's... so it's only good for smurfing. Well, it's a troll build.

Building supporters as "sneaky tanks" can be pretty fun - avoid health while stacking resistance items like Bulwark, Frozen Heart or Abyssal. You're seemingly squishy with less than 2000 health, so people will probably focus you, but at the same time, you've got 200-300 armour and magic resistance, so they're wasting their time.

I've heard some things about AD Elise, but I don't know her, so I can't say anything about that.

Try building crit on Amumu. You'll see why...

Olaf with Lich Bane and spell vamp could be somewhat annoying.

Volibear can be played as an assassin with with Boots of Mobility, Sword of the Divine, Frozen Mallet and 3x Warmog's Armor. You run out of the jungle
