lowballing rhino gambit could smack him with " a" card and ko his @$$..
high end written as he should, Gambit would have trouble hurting Rhino as Rhino would shrug off his cards until Rhino is about to Ko him/squash gambit.
Gambit takes advantage of the situation and releases an entire Deck in his gut.
aside from that i could see a fight goin a good while with Gambit if Gambit doesnt go nasty and charge up Rhino's suit or turns into death.
