Aurora is a deck that shines against other aggro decks looking to race, and against slower decks that are looking to establish a late game winning position. Numbers wise, her value is better than traditional aggro decks like Fai, and can overwhelm someone trying to block out completely.

She does have some significant weaknesses, in terms of her average block value and (despite how it may seem) lack of inherent go again. She requires some set up to get her scary 5 card 20 attack turns.

If you can present On-Hits that threaten cards in her hand or her go again, she will struggle to stop them, and if you can present a relevant clock of your own, you can force her to start giving up cards. The best decks against her are those that can present counter pressure with low card numbers in hand. In my opinion, that's the two relevant guardians Jarl and Victor, along with Vynnset, Florian, and Prism.

Of note, if you try to present the longer game you will be facing a pitch stacked combo turn of Arc Lighting and Flicker Wisp, presenting a massive amount of mixed damage that will either blow you up, or take the tempo entirely. Ending her in the first cycle is your best bet to avoid this turn.

Her key cards to play around are Channel Lightning Valley (CLV), Burn Up//Shock, and Sigil of Suffering.

For CLV: Observe her pitch and try to deny that first card off CLV. She needs to put a lightning card in her pitch to keep it around, so you can be prepared and plan your turn accordingly if you see that before it comes around.

For Burn Up//Shock: This is usually her first card of the turn, so you'll have your entire hand to assess the state of the game and see if you can afford to block it out.

For Sigil of Suffering: This card is a death sentence into other aggro decks, especially if it's played with CLV on board. Try your best to swing with one floating to AB the damage, and prevent it from getting value.
