Barn Dudes

From BoardGameGeek:

In the almost empty lands of Zhokhlystia, you can find a few warring barns. Each of them is full of Barn Dudes that keep the barn standing. Every night, the owners of the barns send one of their Barn Dudes to battle on neutral territory, not knowing what fighter the others will send. They all want to get rid of each other, so the winner will poach the creatures from the losing barn, for as soon as there are no Barn Dudes left in the barn, it collapses on its owner. Gnomes, Spirits, Beasts, Goblins, Creeps and Mushroots six warring barns send one barn dude to battle every night. Win the fight, gather your guards to strengthen the barn and use its unique power. Empty the barns of your opponents, cause only one can survive in the battle of Barn Dudes.
