12 seconds in, you can see Namor with the rest of the All-Winners Squad (that's what the Invaders were called in the Golden Age). He's also in a crowd shot at 61 seconds in (not sure what that's from, but the next scene is the original Secret Wars), and another 98 seconds in (all the major heroes outside the destroyed Avengers Mansion in Disassembled - Moon Knight and Nick Fury are in this crowd shot too). Also Vision IS in the video, right at the end - a shot of him kissing Virginia from Tom King's 2015 series.
The deletion from the Avengers #4 cover was nothing personal - they also erased the Avengers logo.
While Wanda has no focus shots, they did include House of M, which heavily involves her.
