I think that adding anvils into the Eggwars shop could be a cool new addition to the game. They wouldn't be used in the normal way where you could combine weapons and armor, but rather they would be used to deal damage from above. Once an anvil is placed, it would act like a normal Minecraft anvil, but after touching the ground, it should completely despawn. Also, it should use more durability to armor than swords, axes, and bows. Maybe there could be different kinds of anvils that either do more or less damage, depending on price, but either way, I think it could lead to some funny and creative kills. I believe it would be under the miscellaneous category in the shop, and I believe that the price could be either 50 iron or 10 gold for a regular anvil, or 5 diamonds if it were to get a damage boost. Please let me know what you think of my suggestion!
