Alien Theme Deck

[Thallid Ice Cream Man]

I decided a little too late that I wanted to make an Alien theme deck, but the only cards I can think of are Abduction, Probe, and Conspiracy.
Does anyone have any ideas?

Well either use Goblins (little green men) or things like Negators (look like Aliens from Giger).

Or both.
