It attacks and blocks well, and has one of the best group hug abilities Ive seen since Breena
Invasion of Mercadia C-Tier: Basically the battle version of Bitter Reunion, except the ability to give all of your creatures haste is likely more of an upside than potentially flipping into a 3/3, which means this is probably just a worse version of a card that already exists
Shes a great card for players, and a gorgeous card for collectors, and a massively popular character we have yet to see in an Enchanted print
If two or more players' cards are tied for greatest, the tied players repeat this process until the tie is broken
Could include a card that draws when it ETB such as Baleful Strix that way you could infinite blink Strix to draw Omniscience + Acererak, to cast them with infinite mana to combo
Do you expect Battles to be similarly impactful, showing up in every set from now on
