And honestly, you'd have some good opposites in the Magical area keeping the Snow Queen around:

Fire - Regina

Ice - Snow Queen

Light - Emma

Dark - Gold

Light Fairy - Blue

Dark Fairy - Maleficent (This one is speculation)

Still need earth and water (Zelena would have been air, had she survived)
