歯を食いしばる用、最強. 俺の最弱はし賭博響くそう！

This is just what is he saying... by parts:

歯を(ha o?) - teeth 食いしばる用(kuishibaru yō?) - for clenching 最強(Saikyō?) - Strongest

俺の最弱は(Ore no saijaku wa?) - My weakest し賭博(Shi tobaku?) - attack might 響くそう(Hibiku sō?) - shake you up a little

Even not sure about the last phrase, but it's a copy/paste from the index version.
