Both upped and unupped make the same. Other than that, it might be less powerful than Dune Scorpion
So...this card is called Vapor Scorpion...and the effect has to do with freezing?
Vapor and ice are completely different forms of water. Vapor is a gas, ice is a solid. You can't use Vapor in the title and make the effect based on ice, that just goes against nature and logic.
