Even though I originally leaned towards Atyroki's thorny devil, after much consideration, I've voted for aragornbird's dust devil. It can fit the stats easily enough, and the ability could be named something related to desert mirages. And it's definitely not hard to see this using Rapid Spin when it's already a DUST DEVIL.
As to why DougJustDoug's & CyzirVisheen's are getting so many votes, I'm not getting it; while they're both good, one needs to think about a few things: Neither look like they could be seen using Rapid Spin (something I thought this CAP was meant to have after all of these conversations), and both of them look far slower than a Base Speed of 95 would suggest. I know I did vote for both of them in the other poll, but just to weed out the other not-so-good submissions, which was the basic purpose of that poll.
