I gotta give it to Hisoka, his ass is so deceitful and tricky to deal with in battle. His knowledge and use of all the fundamentals of nen already puts Gambit at a disadvantage. Gambit can't use Gyo to see Hisoka's Bungee Gum or any In-based attacks. You want to watch a man sweat bullets? Throw some invisible playing cards that can pierce through flesh.
Hisoka wins to me.
