I was initially on team Chrollo, but after the amount of damage Hisoka's sustained, I'm beginning to pity him. Ofcourse, Hisoka could be resourceful enough and find some way in using his nen to return the flow of battle to his side, but I doubt he'll win after losing large potions of his limbs. Either Hisoka dies, the battle ends in a draw or a third party intervenes...
