This brings the total count to 13.
At the tail end of their Mario & Luigi Superstar Saga + Bowser's Minions stream, Nintendo showed off two new amiibo -- the Koopa and Goomba, that will presumably be launching with the game. As usual no details were given, but the Boo amiibo will also work with the game.
Given the huge minion angle that the "plus" portion of the game entails (with a new battle system to boot) I can see these being innocuous little power-ups.
