If this Deathstroke is anything like the one in the comics, Oliver would not stand a chance in hell of defeating him alone, just look at Identity Crisis, he took on Flash, Green Lantern, Hawkman, Green Arrow, Black Canary, Zatanna, Elongated Man and Atom all at once with little trouble and he only lost through a fluke on Green Arrow's part. If he has even a tenth of the ability this Deathstroke has, Oliver would be ripped to shreds in single combat.

I personally think that should a fight ever arise, in order to take him down it will have to be a combined assault from the entire Team Arrow: Arrow, Canary, Roy and Diggle, ideally they could also have reinforcements, like the Suicide Squad for example, just to put them in with a fighting chance.

I don't think Oliver thinks he can beat Slade one-on-one, I think he will be hoping for a combined assault with his full team, if he does think he can beat Deathstroke alone, then unfortunately, he is an idiot, or he has one hell of a big trick up his sleeve.
