So, if Kabam included the correct silhouettes in the video, I think the unrevealed champions are (from left to right):
Deathless Morbius
I thought it would be Maw but the way he comes forward with his claws looks like Morbius a lot

Deathless Guardian?
I really don’t know, I predict a tech champ with a symbiote on them, I said Guardian because of this shot where there’s the shape of the glove

Deathless Terrax
The boots give it away
