Assuming this isn't a troll post: -Magic Pen marks -Armor/mana regen seals -Magic resistance (flat)/ap/cool down reduction glyphs -Flat AP/Move speed quints. Or, if you want something a little more unusual, gold/10 glyphs.
Tired of photobucket and imageshack? Ask me about dropbox.
I have about 10 pages I use for AP mid lol, look at my profile.
I run; Magic pen reds Mana regen/AP per level yellows Split runes, half magic resist, half AP per level/half flat AP blues. This is so I don't start with flat 30 magic resist. AP/MS quints.
My TF/LeBlanc page I just have Magic pen reds, Flat AP quints and Flat AP everything else. This is because; TF doesn't gain damage at level 6 so per level runes don't make sense, and with LeBlanc I try to kill them pre-6.
