As Flamewar, Brash Veteran, you can sacrifice an artifact to put a +1/+1 counter on it and flip it
Bria, Riptide Rogue and Adrix and Nev, Twincasters are two commanders that leverage these effects well as they apply loads of pressure with their wide board states
Then later, you can cast it any time you normally could based on its card type but for a separate foretell cost, which is often cheaper than the spells mana cost to account for mana already spent
Its value stems from its rarity and its association with Eevee
All of these cards also give you two Landfall triggers at once, which lets you get more out of cards like Nissa, Resurgent Animist
I think the power level of this card is such that it instantly replaces any flex slot burn spells such as Shard Volley, and Im starting to believe that it may just be an upgrade on lower end core spells like Rift Bolt
