Morgana is very good midlane. She has spell shield so she can block stuns, silences etc. and she can get out of ganks very easyly.

These are my basic "Mage" runes. Magic Penetration helps you to deal full damage early, Mana regen runes keeps you on lane for long time if you don't spam your abilities. AP runes are good for start and gets better the longer game goes on.

I don't take spell vamp 'cause Morganas passive gives a lot of spell vamp entire game. Zhonya's is for intiates+ulti. You cannot be interruped if your team keeps enemies in your range. I suggest Amumu or Galio as tank 'cause both of them have ulties that keep enemies in your own ulti.

Depending your team you mostly want take Q first but when you have jungler I suggest W. It helps more than Q since it's lowering Magic Resistance of target monsters. For exaple Fiddlesticks deals a lot more damage if targets MR is down.

Flash is for short teleport initiate. You want to use your ulti and Zhonya's at the same time. Ignite is good against Champions like Vladimir 'cause it's lowering enemy heal effects by 50%.

Try to ask your jugler to give you blue buff. Whit that you can pretty much spamm your skills. If you don't have jungler Morgana should be able to take it herself at level 7 or 8.

Whenever you have time go gank bot- or toplane. If you have killed your enemy in mid and you are more than 50% of your max HP you can gank. BUT MAKE SURE THAT YOU TELL THE LANE BEFORE IT'S TOO LATE!

When your W is level 3 use to caster minions they should die if they stay the whole time there. Otherwise just last hit melee minions.

Protect low HP champions with E. E has spell block and player who has it on, is unable to get slowed, stunned, knocked etc. You want to place W center of the battle most of enemies are damaged by this.

Pros:
-You can snare enemies for long time making your team able to catch
-You can protect/help friendlies away
-Mass stun

Cons:
-Abilities cost lot of mana. Using them all the time takes your mana fast.
-All items are very expensive so you must get kills, assists or farm a lot.
-Can't do much without abilities

This is my second build. I made it at the same day when I did my Shyvana build.
