Guild's Artisan 1R
Legendary Enchantment - Background (Uncommon)
Commander creatures you own have "Whenever this creature attacks a player, if no opponent has more life than that player, create two Treasure tokens". You have a critical eye for valuables, so it's almost impossible to deceive you.
Just like Barbarian Class, we get a red enchantment with a new subtype before Wizards gets its day 1 spoiler dump. This one helps us transition from Treasure-heavy New Capenna to... possibly Treasure-heavy Baldur's Gate.
(anyone who hasn't seen the leaks, feel free to guess what Background does for the next hour and a half)
Wulfgar, Jolene, and Isshin all make this potentially mana-positive on the turn you play this (assuming you play it after the commander). Partners also play really well with this and I can imagine seeing low curve decks with Rograkh using this, though the potential ability to pay 2 mana and generate 4 treasures that turn may even let this card crack certain cEDH lists.
Cheap commanders like Zurgo Bellstriker and Ragavan allow this card to be mana neutral even if you play this card on curve and this card likely has a place in nearly all such decks.
I know that some people are going to see a treasure token and instantly have their mind go to Korvold but I'm not actually sure if this is good enough to crack the tighter korvold lists I've seen
