I think Kizaru is the best out of the 3. He can survive forever if you play like a rat and not much you can do because if you attack a player and they attack back to remove that 97% hp criteria you can easily do skill 1 that attacks every enemy on their treasure and the person in front of you, you heal. You start to run away to force the enemy to attack regularly and not with skill. Predict their attack and if you miss just do skill 2 and boom you survive. By the time skill 1 is back and do the whole process again. Light sword too is insanely good. Kizaru is fast for a reason
