Why this duo works
A likely reason this duo performs well is that Maokai's roots hold targets in Miss Fortune's Bullet Time(R) cone, letting more waves connect. His engage also gives her a clear follow-up window in lane.
Playing the duo
Maokai's Twisted Advance(W) roots its target and Nature's Grasp(R) roots enemies in its path; those immobilized targets have less room to leave Miss Fortune's Bullet Time(R) cone.
How to play as Miss Fortune
Follow Maokai's W or R crowd control with Bullet Time(R) while the target is held; if the target is not already rooted, cast Make It Rain(E) first to slow their exit from the cone.
How to play as Maokai
Engage only when Miss Fortune is close enough to follow, then use W on a priority target or R across the grouped team and call for her Bullet Time(R).
