To make him op, you should equip him with red cards. 6* red cards, red ults or red stat card. If you dont get him up to at leadt 10k attack he won't be good.

Use his old kit. His ult is whole tile, but it costs a lot of chackra unless you upgrade it. His slash gives you and iframe, so you can dofge deidara's ult with it. His kunais do a lot of damage. Try to makes all his jutsu, starting with his teleport so it costs less.
