Pros:
One of the best stuns in the game
Is very good for teams
Her shield can block every cast
Can chase very good
U can take sololanes because of your passiv

Cons:
Not much hp so can die fast
U need a lot of farm

Dark Binding:
A great stun, one of the best stuns in the game. A big range and long stuntime, perfect for everything. For ganks, teamfights, 1 vs 1 and for defend. At first I would train how to use it.
You can cast it trough walls, but watch out for the minions they are bad for your stun, bad, really bad. ok?

Tormented Soil:
It makes a lot of damage and is great for farming. You must make always a combo with your stun, stun him then make the soil, that's your nuke. It's not really dificult to use it.

Black Shield:
This is one of the best spells for defend yourself or your teammates. always watch out for people who need it. I have a little trick for doing the spell faster on yourself. Press Alt and then e. Now the spell is automatically on yorself.

Soul Shackles:
Your Ulti. He's great, he slows enemys, makes damage and stuns at the end. You can use it for chasing enemys, run away from enemys, help your team to kill enemys and so on.
A little trick when you stand nearby a bush and a enemy is in the bush. You can use your ulti. When no enemy is in the bush the ulti is off.

Normal Masteries and Runes for wizards. I think all is clear^^.

I start with Doran's Ring becaus you become health, AP and mana regeneration, perfect. Then I buy Sorcerer's Shoes or Mercury's Treads. Why Mercury's? Because it's really bad for you to get stuned but Socerer's shoes are also good. Then I get Archangels stuff, because it one of THE best Items for Morgana. A lot of AP and Mana, what else. Void Staff is just for Magic Penetration but you can also take Deathfire Grasp. Then i take Morello's evil tome for the Cooldown and Mana. Rabadon's Deathcap gives A LOT OF AP. The hourglass is just for Runaways at last. Why I didn't take Rylai's Crystal Scepter? Because your stun slows enough and your ulti too.

Stun, stun, stun. stun them and then make your Soil on them. Always use your shield on mates and on you and chase enemys with your ulti. But you must be very careful.NEVER go alone or run at first into the fight. You don't have so much live, be careful. Buy wards and place them by Nashor and the dragon. You farm with your Soil the creeps.

Well that's it.
