Nice, a little more patience. He's definitely worth it!

I hold my group leader's account and he hasn't come back lately, leaving his Deidara halfway to 4 star.
Seeing Deidara in battles especially GNW and ranked battles just leaves you in awe of his ability to just nuke anyone that gets in his way.
You can have him with Earth main for a very solid comp, or run with a glass canon azure fang sage passive build. xD
