How to beat Seraphine as Yuumi: the early game

Levels 1-3 belong to you: leash-free and push for the level-2 spike, then abuse empowered Q pokes from behind your ADC. Seraphine's E root is single-target and short, and without it she can't lock you for her Q combo, so respect only her E cooldown and trade freely whenever it's down. Her ramp outpaces your healing if the lane goes long, so keep the speed up and let your carry farm. Stay attached, aim the missile only in the gaps her casts leave, and never detach while her root is available to catch you standing still.
