Fatman
3 turns
Ultra rare
Places a Fatman adjacent to a friendly mechanical unit. When the duration expires, all immediate units within the vicinity take massive damage. Deals 200-250 damage, with further hexes taking less.


(if you don't know, Fatman is the nickname of an atomic bomb)
I can see a card like this being strategically used, maybe even to ward off a rush. The blast cannot penetrate cliffs/walls, so if your unit is directly on the other side of a nearby cliff/wall and is out of the line of site of the fatman, it will not be effected. And of course the blast is limited to a certain radius, but considerably larger than that of an artillery attack or any other explosive cards.
