Normally, I just get one social media preview card, but for Unstable I was able to get a Blogatog exclusive preview card.

This card started life in a black bordered set as Elephurtle. It had an activated ability that allowed it to swap between ¼ and 3/3 (I think it was base ¼ and could gain +2/-1 until end of turn). 

When I moved it to Unstable, I was able to stretch its ability a little and now it can be either anywhere, anytime. 

So, Blogatog, please welcome Shellephant.
