Perhaps Super Smash Bros Ultimate is the best smash game so far, and now it will become more interesting as previously data mined Stage Builder mode could make its way into the game very soon.

Recent Smash bros commercial posted by Nintendo on YouTube accidentally leaked the stage builder mode. The screenshot was taken at 0:02 sec of the video clearly highlights the blurry Stage Builder written on the main menu.
Stage Builder mode is already seen in Super Smash Bros. Brawl, and Super Smash Bros. for Wii U. This famous mode allows the players to create their own custom stages using various interactive components.
The mode was previously uncovered by data miners and has now been shown in the Nintendo commercial. We may hear the addition of this mode to the game very soon, maybe at the next Nintendo Direct.
