A man in a top hat is shown driving a car, while reading over a letter in a hand-drawn style scene, with the SSB logo in the bottom corner, with a boy looking at the letter as well, asking him what it is. The man chuckles, and tells him "Luke, my boy, it's something bigger than you'd ever imagine..."
The scene then cuts to a CGI scene in the boxing stage with Mario, Link, Kirby and Pikachu duking it out, before the man walks inside, still in the handrawn style, and they turn to him in fighting stances. The man proceeds to pull out a sword and become CGI, the background changing to orange, and a catch-line appears next to him saying "Professor Layton Solves the Puzzle!" (Or something less stupid), and gameplay of him is shown, with Puzzle Battle playing in the background, before it cuts back to CGI, where someone calls out and Luke jumps down next to him, becoming CGI as well; gameplay of them as an IC style duo is then shown (maybe with Luke's theme playing in the background), before Layton smiles as the Laytonmobile drives up to the two and they get in, and it enters it's flying form, the video stopping as he flys towards Mario, Kirby, Link and Pikachu, with each one running away, before it cuts to the logo, and Layton doing his "Correct!" animation from Miracle Mask, and the logo splitting into two following it, with "2014" appearing before the trailer comes to a close.
Alternatively;
Mario, Link, Pikachu and Kirby are all on a St Mystere stage, trying to solve a sliding puzzle. Someone then taps them on the shoulder and offers to help, and solves it...before performing his "Correct!" animation and sending them flying, with it then fading to the orange background with the catch-line "Professor Layton Solves the Puzzle!" appearing. Gameplay of Layton is then shown on that stage, before it cuts back to CGI, with Luke running up to the professor and offering a hand. Layton smiles and nods, the trailer cutting to gameplay showing them as an IC style duo, before the professor stops fighting, cutting back to the CGI, with Layton and Luke getting in the Laytonmobile and using the flying form, flying towards the group, who are running away, the trailer freezing. It then cuts to the logo, and Layton doing his "Correct!" animation from Miracle Mask, and the logo splitting into two following it, with "2014" appearing before the trailer comes to a close.
