I'm fan of grifter, so this is really breakin' my heart, cause I think the winner would be this good old cap, why ? Cap has a lot more experience in fignting anything Grifter can throwing him and is the utlimate Soldier : Grifter would Shoot him, Cap can dodge Bullet (Comics paradygm, thank you !), he can attack with his TK, but Cap dodge and find a way to coerce this power by tactics. After all that, few acrobatics feats between te yellow cabs of the Big Apple, maybe a great deal of collateral damage, Cap would go to Hand-to-hand, and even if the Grifter is not a Slouch in this Domain, Cap has been Fighting, God, Aliens, Other supersoldier and many other threats for more than 5O Years, Grifter is good, but he has yet to fight the same scope of ennemy in his history. So Cap would burly him and leave him Knock Out with a John Way replica like :"Good Triyng Soldier, your were close, but no Cigar !"
