User blog comment:Mineko Charat Lucky/Stop Telling Me What to Build, Thanks/@comment-4434378-20131015182203/@comment-8267817-20131019135707

Teemo with Runaan's makes sense, aoe posion without having to stop and be a mushroom farmer, BotRK works fine on Graves if the enemy team is tankier and has a lot of health and you do more than just buckshot and run.

Merc Treads on Sona doesn't make a ton of sense to me, but Tenacity is good on everyone lol, though other items are available for it, perhaps she didn't feel another kind of boot was apropriate at the time.
