I've been playing Morgana in the mid lane for a while now and want to get the right runes for her. I've been using the standard flat ap quints, flat ap marks, armor seals, and mr glyphs. I'd like to get runes that go specifically to Morgana. Thanks!
Gallowgrim1 votesI actually prefer Scaling AP for her. Midlane clearing power is pretty high due to Soil, and thus farming potential tends to level you pretty fast unless hard-focused.
And Morg with enough AP is a monster.

Drunk Rummate1 votesCDR/level blues, scaling health yellows, mpen reds, AP quints.
cdr/level lets you go sorcs or mobies for more midgame power. morgana scales really well to 40% cdr because it lets her throw out a ton more bindings and shields and the mana cost on those abilities arent super restrictive.
Carterfilly1 votesThank you! What's the reason for the scaling health yellows? I feel like i need some MR to survive lane a little better

Scaling health works better on AP carries in general because you aren't taking a lot of phys damage due to higher range and going in and out based on your cooldowns. Health seals prevent you from getting blown up as easily in the period of time that you do commit.
Also, morgana builds Zhonyas as a core item so you get enough armor from that.
For laning, most APs generally take either CDR blues or scaling AP blues. Only reason to take magic resist blues is if you're laning against an AP assassin like Diana, Leblanc, or Ekko. Morgana actually has her spell shield to deal with that though, so she's pretty resistant regardless.

SnugglePuggle941 votesThose look pretty good, but my secret-I grab one Spell Vamp quint. Those along with the spell vamp utility points in your masteries, along with 
(not necessarily in that order) and I think one other but I can't remember, along with her passive, you can get a crap ton of SV. You don't have to do that though.
