There is speculation thatSuper Mario Maker 2will not have amiibo support. Reddit user realestmemoryman3 posted on the Mario Maker Reddit a link directed toa Gamefaqs thread. In the thread, there were comparisons of different first-party Nintendo Switch Game posters includingSuper Smash Bros Ultimate,Yoshi’s Crafted World, andCaptain Toad: Treasure Tracker. On all posters of the respective games, there are amiibo logos on them. However, there is not an amiibo logo forSuper Mario Maker 2.
You can see comparable examples below:

Super Mario Maker 2:
In the originalSuper Mario Maker, you could use specific amiibos like Link fromThe Legend of Zeldaor Marth fromFire Emblemto transform Mario into the respective character in sprite form. Mario would get this form by picking up a mystery mushroom. The 30th Anniversary Mario amiibo, if used, would spawn a Big Mushroom power-up to make Mario gigantic.
