I'm sorry to say but Trundle does not belong in the lane at all and DEFINITELY not in a solo top setup, he will be eaten alive by champions like Udyr, Yorick and Irelia who dominate solo top. The bottom line is he is a farm-dependent melee champion who lacks a gap-closer and will be harassed out of top lane constantly. That being said, he is in my honest opinion the strongest jungler in the game, very well rounded in all aspects of the jungle champion, and he belongs in there.

Now onto your items, NEVER buy Atma's Impaler before Warmog's Armor, because that's just dub, especially when Warmog's has to be farmed and it is the second to last item in your build where you will likely not be getting much far mat that stage of the game. Also, Last Whisper is a very situation item that you shouldn't include in your core, although you may mention it as an alternative for enemies stacking armor. Overall I don't think Trundle benefit's too much from Wit's End either but that's a lot of personal opinion. Last but not least, why the hell did you take Archaic Knowledge ?? What exactly is that supposed to benefit on an auto-attacker?

Sorry mate until these critical errors are changed it's a big -1 from me. You have played Trundle before right? I cannot imagine anyone getting success with this setup.

Sorry, lane trundle is quite odd. To be honest I see no real point in getting a Tiamat since really excels at focusing down one single target. After all, his Q and Ultimate are made for that. Trinity force is so incredible on Trundle and I'm really surprised you don't end up buying it. May want to rethink your item choices.

-1 for me trundle should never lane he is made for jungling and he excels at it so there's no point of laning with him

Thank you for this comment, i'll check your advices and gonna test them in some games, but it sounds very logically.

+1 gj, just a few comments. first, the synergy of Trinity Force with Rabid Bite is great. also, you'd need more max hp or crit chance to really use atama's impailer as a better option over Infinity Edge. with that said, however, i personally hate those two items on most of my champions. i just feel that they work well for trundle. i also question the point of Archaic Knowledge on trundle. as mainly an auto-attack based champ (in my opinion), i don't see why you would take that when Sunder would serve you better.

i do like it, looks well done. just could use a bit of work.
