My only worry is about the dragons. The point of this deck is to beat earth's otyugh spam, and dragons + frogs, as we saw, doesn't work. Maybe you'll be able to mutate away devour.....
Of course, you can always mutate the dragons to something else...
And they're too big for devour....
You know what, I'll trust you. Go for it.
I just worry about how reliant you are on rustlers, and how easy it is for rustlers to be killed.
