#2 Elsa The Fifth Spirit I was excited to see this card revealed because of how needed it is in the current meta, especially for Amethyst decks
The Sapphire/Steel deck accelerates resources to cheat out big characters early, the Emerald/Ruby deck had lots of character removal and ways to steal Lore from the opponent, and the Amber/Amethyst deck had lots of card draw and could pull off many tricks and combos
I have no idea how flavorful these pairings are, but the original Partners werent always super flavorful anyways, right
Sapphire ensures steady ramping, giving you the ink you need to fuel strong late-game plays, while Steel provides raw combat power to protect your questing characters and eliminate threats
