Rivet

Origins
This zombie is based on a rivet, a metal pin or bolt for holding together pieces of metal.

With
This zombie may be weak, but its exclusive Team-Up allows it to shield other zombies from damage. Because it is a Machine zombie, it has synergy with other Machine cards. You could also use it to block a card such as Doubled Mint for a turn until you can destroy it.

Against
If this zombie is protecting something strong, you can use Whack-A-Zombie, Squash, Time to Shine, Plant Food, or a Freeze+Winter Squash combo to defeat it. You could also use Splash Damage, or cards with   Double Strike. Overall, if not buffed, this card is not threatening.

Trivia
