I got Greninja'd
Anyways, this is how I could see Shulk's trailer(very similar to the above quote):
The trailer starts with Ness and Lucas getting thrown around, like the start of Lucina's trailer. Lucas is cowering behind Ness, who's still standing somehow. You get a glimpse of who they're fighting, none other than Mewtwo. He even has a newcomer tagline "
Mewtwo Strikes Back!" The entire scene has a bluish tint to it, however, it's so minor that only people in fullscreen with good eyes can see it. We see some gameplay of Mewtwo, and then it's back to the CGI. Mewtwo unleashes an attack that finishes Ness and Lucas off, then the screen fades to black. At this point, most viewers are going, "WTF?" Then, the same scenario plays again. Ness and Lucas get knocked around, Mewtwo, etc. Except, this time, when Mewtwo goes to finish them off, a yellow aura envelops them, shielding them from the blow. Mewtwo, confused, looks around, only to narrowly dodge two green slash marks. A shadowy figure appears in the sky, and you hear the words, "Monado...BUSTER!" As the Monado narrowly misses Mewtwo, who dodges out of the way at the last second. Shulk lands on the ground, stands up, and his newcomer tagline appears: "
Shulk sees his way into battle!" or, as previously suggested (and way better) "
Shulk engages the enemy!" We then cut to gameplay footage. Shulk has a powerful moves, including Monado Buster(Neutral B), Monado Purge(Side B), Monado Shield(Down B), and Monado Cyclone. He has two special mechanics. His Smash Attacks are Stream Edge(Side Smash), Air Slash(Up Smash), and Shaker Edge(Down Smash). If you use Air Slash or Stream Edge on an opponent, they get Break, this lasts for about a minute. In this time, if you hit them with Monado Cyclone, they get toppled(The tripping animation), follow this up with Shaker Edge and they get dazed(The animation that happens when your shield breaks or you get hit with a Deku Nut). He'd also have a tension system. His character portrait in battle changes based on the amount of hits he gets in on his opponent/how many times he gets hit. Get a good combo going on your opponent, you do more damage, your opponent gets a good combo going on you, you do less damage. Keep a somewhat even ratio of hits between you and your opponent, and you won't be affected much. Anyways, the gameplay portion ends, and the logo appears. Afterwards, you see Shulk helping Ness and Lucas up, his eyes turn blue, and he drags both Ness and Lucas back as the ground they used to be standing on explodes. Shulk looks up, and the camera pans to none other than Snake. "
Snake blows up the competition!" The screen then fades to black, with no gameplay of Snake.
How's that?
