With Blythe from 3 Houses being added, it makes what for something interesting.

So with the new DLC pass, there is a chance for Astral Chain Protagonist to be included in. It is a newer game but relatively the same age as FE: 3H. Which is exciting because Astral Chain is fun and great addition to Smash, I would think.

So Yea. And of that happens there is a very slight chance that the mii costume for 2B (from Nier Automata) could be added! Which is a dream of mine, love that game! (Saying this because it's made by the same people who made Astral Chain)
