Winrate by number of games the summoner has played on this champion.
•Play lane with short off-on trades: detach only after the engage spell is gone, use one auto or eat one blockable projectile with your HP, then reattach before your W punish window opens
•Yuumi Q needs a driver—cast it from a host whose movement gives the missile time to arm and steer, because the real slow comes from travel time and gets better on your Best Friend
•Treat Best Friend as a lane bet and keep the game attachable: Yuumi gets less from early off-lane roam kills than peer enchanters, but one of the biggest long-game lifts in the role if you stay on the seat that can still carry later fights
