Hei,

this is my first guide, and its something uncommon. Please excuse my bad english.
We are talking about Morgana Support. I hope you like the guide and give me some feedback.

It works perfectly with adc which have:

a dmg-Ult (Not sth. like Varus)
A high scaling dmg-Spell (Mf Q)

My favourit adc for Morgana Support is defintly Mf. Its a real WomboCombo when u hit ur spells right (read below)

Laning
Fighting
Try to stun the adc, than immediatly try to catch the support and the adc with ur ult and save ur adc with your shield from any stuns.
Get ganked
Save your adc again with your shield from getting caught.

Lategame
It's pretty much like a midlane Morgana
You should have skilled your w now and can easily depush lanes and get some farm.

Always keep the important positions warded so you have vision to all 5 opponents to time your Solo-Wombo-Combo.
Its important to do it when the opponents are hanging around crowded.

You should wait for your a engage-champion to do his job. Activate your Shurelyas to follow him quickly. If you're close to the adc try to exhaust him and activate your twinshadows to slow (with exhaust on adc) 3 opponents. Now its time for your ult and your Zhonyas to make sure that you dont die before the ult stun hits. Your team should have been arrived now and doing the dmg. When your back out of Zhonyas try to stun the focussed targets with q-w combo.

Like this you will be a great support which can engage.
To make its perfectly try to make sb play malphite when he ults all 5 when u activate your ult this is a really amazing wombo-combo! Gl with trying it out!
