Whispthera trade??

I am still newish to the game and am not sure about creature values. I am wanting a whispthera species and was wondering if anyone could help give me some insight.

I have a eigion warden I'm willing to trade for it along with other creatures like asemir, starknol, veludorah, and raiquazok. Do you think anyone would take that trade or should I take my chances with getting a death token??

Someone please help-
