Okay so im currently a ****ty p4 support main who also seems to be getting autofilled adc a lot and since people are sleeping on mf here's the guide for her. you want to be aggressive early, you want to get early leads, and you want to snowball. No matter how good mf's early game is with lethality, it falls off like a boulder off a cliff. do your team a favor and go crit. yes i know you need 3 items to become a good champ, but pta makes up for that. get your team to play around you just till you have a slight advantage (ie bf sword to pickaxe) stomp and snowball. get plates, rotate top, get those plates, get drakes and freeze wave to deny the enemy cs whenever possible. because of your q, you are able to threaten to chunk out the enemy adc early by keeping one caster low in the enemies wave. this allows you to chunk the enemy out whenever they try to walk up to last hit, and unless their support can cc you (ie flash flay from thresh) you should be able to do this for free
