I just thought of the scariest combo with the new duskblade
on the wiki it says > As with Sheen, the damage of Nightstalker matches the triggering attack. If triggered by Corki, it will deal 80% magic damage and 20% physical damage.
> Similarly to the above, any ability that amplifies the attack's damage will amplify Nightstalker's damage.
and also it being a no CD proc gated by how many stealths you have.
enter 
with a spammable stealth and an aa buff on q (maybe, dunno if that counts for the bonus damage)
don't tell me that's not a scary thing to face.
