Question: who synergizes with miss fortune?
Answer: Leona, Nautilus are some of the best. However Lissandra can be a good support for MF as well. Both champions become immensely stronger at level 6 to the point of becoming an overbearing lane. Leona, Braum, Nami, Sona, Rakan, Morgana, Zyra, and Sion all come to mind.
