Living machine: Cyborg, which is a hybrid of living and prosthetic parts.
I did consider that! What I was actually looking for however, was not "living creature turned into machine" but actually "machine turned into living creature." In a sense, a evil-malignant-cell-thing that controls and infects machines to try and take over the world. I guess it would work if you think hard enough. xD
Catapult...
I considered that too for a brief moment. A problem I found during my
vigorous testing was that the Armagios would never be used for defense if a Catapult was gotten out somewhat early. Then I figured that it would be cool if s/he could use a different strategy every few matches. Therefore I'm only adding one copy though, so that the Armagios could be used for both offense and defense.
