He has no mastery with any kind of weapon (WB had his bisento,Shanks a sword, Kaido a club and BM a sword as well) so he will probably miss and sink the ship or some other crap lol. Anyway either at the very end of Wano to symbolize he has finally reached yonko status (maybe a brief moment of super power up) or in the next fight alone vs a yonko or yonko+ level villain.
