Morgana's core lies in landing her Q and timely protection with E. Dodge her Q with good movement, and use E effectively against enemy grabs or CC.
When using her ultimate (R), combine it with Zhonya's Hourglass to ensure stable teamfight contribution and survival.
Prepare for her CC combos with Cleanse or Quicksilver Sash to nullify her crowd control.
