Thankfully, this is a long-established archetype, and there are plenty of cards that make such a deck viable
You can tap any untapped artifact you control to pay the cost of the mana ability, including an artifact creature you haven't controlled continuously since the beginning of your most recent turn
It is only triggering off of Princesses but wants to go in an aggro deck, but most Princesses aren't really aggro cards
If youre a fan of that set, and older sets like Dominaria or just of Final Fantasy as a franchise then this format will be a delight
You can also try to get a Support character like Huey or Dewey out on turn two or three to ensure that your four-cost character can banish whatever Maid Marian targets, but a Maui, Soaring Demigod will almost always do the trick
And I had earmarked one: a game called FINAL FANTASY
