The Srumpanzerwagen A7V

Crew 20, Protection from everything.

At the beginning of your pre combat phase, destroy 8 creatures. They cannot be regenerated. Whenever an opponent loses life, you gain that much life multiplied by the amount of infantry you control.

If you control 4 super tanks at the same time, and if you have attacked with all of them once, you win the game.
* is equal to the amount of life you have.

"Nicknamed the moving fortress, see why?"
