This filter makes it so hard to give long explanations. The "increase stats just for full hp members" and front ROW attacking standard is why he is good. I wouldn't underestimate his AOE mystery either, while on the contrary, I believe his chase to be his weakest trait. Having an extra 20 chakra round 1 means you c*e 2 mysteries and possibly eliminate 1 ninja or control 2 ninjas into round 2 (If you immobile after a character standard attacks, they will stay immobile next round).
