How to play as Karma
Use early Inner Flame(Q) pressure and punish Yuumi when she detaches; her laning is vulnerable before the attached pair can safely recover from trades. (Unverified: no source confirms this note.)
Only turn a poke lead into a commit when your ADC can follow up. Karma mains note that Yuumi is much easier to punish with a partner who can act on the opening, while an even lane lets Yuumi scale into a difficult late-game support. (Unverified: no source confirms this note.)
Yuumi's Feline Friendship(P) restores her health after she hits a champion and passes healing to the ally she attaches to, which can undo some of Karma's poke if Yuumi finds a safe chance to detach and proc it. (Unverified: no source confirms this note.)
