This can be a very underrated Inspiration ability I think. I initially didn't think much of it, seeing the dolphin symbol isn't usually followed by something exciting but that boost in water and giving out transporter is awesome.

Ohhh yeah. This one's gonna be an early-round draft pick when I'm filling my Avengers Round Table. I'll probably never use the Call In Help, so almost any Namor will do, though of course bringing in Phoenix Five Namor using the Avengers Assembled function of the table would be a pretty epic story.
