Alright so I pulled Gakido in treasure and I am wondering if I can make a decent formation with him. I tried a couple different ones in Arena but I just feel like he's useless/not-as-good as other supporting types, like Kurenai for example, without also having the other Pains.

Also, any tips are very welcome, if you see that I can make a better formation with the ninjas I have then please do share! :)
My current summons are: Ninja Monkey, Bull and Small Katsuyu. I use Ninja Monkey with the pictured formation.
