meh, he's slightly above bones and ds at throwing things, but both have crazy accuracy and superhuman levels of speed to boot, + healing factors. ds or bones could pretty easily parry anything he throws(dd has made a career of doing that) and when the starting gap is closed he'd go down to either one pretty quickly.
Id say he's the best marksmen here, just hasnt got the physicality to do a goddamn thing if they come close, if he had the all round speed and strength, he's already got the skill he would be the toughest here, but sadly hes a human who uses random shit and throws it at peope and/or cuts throats with straws
Crossbones is MY DUDE I Got Figures, Shirts, and i cant wait to see him in the Movie. DeathStroke and Crossbones are my Favorite Villians that have squared off against my favorite heroes i say that these to are the Epitome of Bad Ass they take this.
Deathstroke could Handle Bullseye but i say they are even Feats wise i mean Bullseye does Have Adamantium Bones so taking him out will be a challenge but DS has Beaten Bats Before so It would be a Good figth
CrossBones on the otherhand i would love to see Him Dish it out with Bane i mean he can Kepp up with Captain America who beat Bane in the Comic, but Bane has beaten Bats as well so that says something about his H2H even in the New 52 he Beat and Broke the Bat its a damn good fight and wish it were an Animated Fight i like All these Combatants but in the end i saY Team 1
