Duskblade seems kinda crazy...(theoretically at least)

Let alone on assassins that can already 100-0 you without help from it.

Especially on bursty champs like... Graves. He already smacks you for massive ability damage...Now his first potential crit after his burst will ensure you're fucked. Thankfully Ezreal can't really use it efficiently (I think).

I thought about Kat too but realized she doesn't really auto attack (even if she has that random high AD ratio on her ult).

^On that note, Akali?

Noctourne does pretty fast damage (especially if he ults first and has some decent AD/AS).

Xin's new crit mechanic ensures he'll be doing consistently high damage, and since he usually builds AS anyway, it'll be pretty hard damage if he can get that last hit off before the 2 seconds is up.

Possibly Udyr with his new jungling item to play with. But ironically, he would be using Q more often with it for that better dps. unless they're heavily anti-AD itemized.

Corki maybe?

Yes, I'm acting like it doesn't have a ridiculously long cd, but if you can eat at least one person with it, unless the teams are even (or in your favor), that can end a game alone late game thanks to S6 balancing.

They're probably not too efficient on most of the champs on this list even. I'm just throwing thoughts around.

But otherwise, other than the passive, it has the highest AD (from what I remember) on an item since IE with 80 damage or old Maw (not including Manamure/Muramana).
