Smash Apprentice
So, apparently there is a new Spirits update for Smash Ultimate where it's a chance to obtain Mario-themed spirits and there will be new exclusive spirits to be added as well. I think there's two spirits from Super Mario Party and a golden mushroom spirit, so that's interesting. Maybe we'll get new spirits from the Kirby series pretty soon that wasn't added at launch like Taranza, Adeleine, etc.
