I use him in 1v1 team and my PVE comp. While he was available through a top up event for the new server and then again for a stamina event but i believe you really only had the ability to get him 1 or 2 star from it.
I love having him for his ability to shield my ninjas as well as buff them. He brings a great tanky front line with decent base Resistance/Defense. His ability to dodge autos and mysteries is an added plus as well. His only con is no real chase just a trigger combo. He also brings an interrupt as for his mystery. He's just a great overall well rounded ninja and definitely worth adding to your team.
Overall He's good early/mid/ and I'm sure into late game. I'm sure hell be brought back sometime? Maybe not for a while? But would love to get him +Stars.
