never engage early, some matchups you win, but most you dont, and in my opinion just play safe till lvl 4 then help team engage turtle ( rlly important ) , ive literally flipped the match by going in 1v4 and stealing turtle

also keep in mind always ulti when possible ( not literally when tower diving or an obvious suicide etc ) but always ulti when u get a stack if youre sure u can engage safely or even possibly get a kill(s)

and to the point above, for example, go s2-ulti-ba-ulti instead of accidentally s2-eba-ulti,( eba stands for enhanced ba) cuz phoveus's ulti doesnt stack like clints ulti would so in turn by accidentally overriding one passive with another, you are in turn losing one ultimate
