Firstly im sorry if this is in the wrong place, kinda new to the forum altho been playing the game for some time.
I was just thinking that it might be an idea to add the 3rd evolutionary stage of the Graboids, the Assblaster would be quite an addition, change the Shrieker ability of burrowing which as far as im aware they couldnt actually do anyway and have them evolve again into the Assblaster and you have 2 options here for there ability either give them Dive for extra damage that way or have them explode when they die (maybe a weaker version of the Unstable Gas cards effect)
I did search to see if this had been mentioned before but i couldnt find anything so am sorry if has been suggested before.
Jeze.
