Morgana

Strengths

Shrewd use of Black Shield can determine the outcome of team fights.
Items that provide survivability allow Morgana to become extremely difficult to kill in conjunction with Black Shield and Soul Shackles.
Tormented Shadow is an excellent farming tool if you're by yourself in a lane.

Passive · Soul Siphon — Morgana drains spirit from her enemies, healing as she deals damage to champions, large minions, and medium and larger jungler monsters.
Q · Dark Binding — Morgana binds an enemy in place with dark magic, forcing them to feel the pain they've caused and dealing magic damage.
W · Tormented Shadow — Morgana casts a cursed shadow on an area, damaging enemies who dare stand in her dark circle. They receive magic damage over time, which increases the lower health they are.
E · Black Shield — Morgana anoints an ally with a protective barrier of starfire, which absorbs magical damage and disabling effects until it is broken.
Ultimate · Soul Shackles — Morgana unleashes the full force of her Celestial power as she unbinds her wings and hovers above the ground. She lashes chains of dark pain onto nearby enemy champions, gaining Move Speed. The chains slow and deal initial damage and, after a delay, stun those who are unable to break them.

A suggested 5-lane lineup built around Morgana, based on hero partnerships and role synergy — not win rate.
