best card in mtg The New Cards From Avatar: The Last Airbender The Top 10 Coolest Magic:

Sapphire ensures youre never short on ink, powering up your bigger plays, while Steel provides tough characters and combat tricks to protect your side of the board

Unfortunately, seven mana cards just arent really playable in current Standard, and this feels too low-impact for Commander

The other character on the front of the box is Sleeping Beautys Aurora, Dreaming Guardian

It is worth a mention that this card pairs well with Bruno Madrigal - Undetected Uncle

You can sometimes "splash" a third, playing two colors as your base and a couple powerful cards or additional costs of another color, but I'd really focus on the two colors you want here
