Wolverine gets knocked out first. Besides the poisoning, Deathstroke or Deadpool shoot them. In the face. Same with Sabretooth.
Which, at this point in time, it becomes Deathstroke vs. Deadpool. I do believe that Deathstroke has some sort of pre-cog/extremely acute senses. I mean, didn't he shoot Kid Flash in the knee while he was running?
I'd say in order of defeat, Sabretooth, Wolverine, Deadpool...
DP and DS fire their guns and put holes in the obviously large target first.. .then then try to hit each other.. but as both are notoriously agile and fast, they dodge well... and get wolverine in the crossfire..
The guns go down.. and the swords come out... and deadpool... ends up dead.. in a pool of his own blood.
Btw.. supposedly if i remember right, deadpool was cured of his cancer when they gave him his healing factor. however the healing factor was successful after the horrible scarring surgery that was required to implant it. Deadpool is horribly scarred because his healing factor wasn't in effect yet when he was scarred... so now he's permanently scarred.
Deadpool takes second though.
