like the title says "the potato has patient and versatile"
to beat fireballs you realy need to EAT Chipdamage dont let it get on your nerves and do stupid shit like EX-Lariat eat the damage and move steady forward learn patience
My game moved up quite a bit after i learned to keep it slow and move inch for inch it realy helps here. Dont forget Hugos Focusatack its good and fast (compaired to his other atacks)
And dont be readable use diffrent ways to move in… dont allways jump use all the ways he has to handle fireballs and try to learn the spacing for jumping.HP but it can be punished so dont abuse it
honestly a good guile is hell if you manage to beat him with patience and versatility im impressed… everything else seems managable
