The game has gotten new skills and Archetypes added in, shaking up the entire format
Firespout is a nice sweeper that can get grounded creatures, fliers, or both
The rest of Vivien is good, if nothing particularly noteworthy
The other most basic payoffs are from abilities that trigger when creatures get destroyed or removed from the battlefield
On the other hand, a lot of good Goblins in Historic currently aren't being used in the Muxus build, like Goblin Ringleader, which, combined with other new additions Sling-Gang Lieutenant and Munitions Expert, could make for a more Modern- or Legacy-style value Goblin shell in Historic, which likely would want at least some number of Pashalik Mons
While I definitely favor the Amber and Amethyst deck, I still enjoyed Ruby Steel immensely, and whether youre a longtime fan or just jumping in, I think the Reign of Jafar starter sets are some of the strongest in the game to date, and it will not be leaving my Lorcana rotation anytime soon
