Aurora has a very strong top lane presence, making her a good blind pick if Irelia is banned, and she can dominate trades from level 1.
Leverage Electrocute and her mobility for strong damage and poke; her wide-area ultimate is highly impactful in teamfights, so consider building 'Malignance'.
She is squishy and vulnerable to bruisers in the late game; be cautious with E skill usage as she becomes susceptible to gap-closing abilities afterwards.
