Rather than just a pixel reward for guild wars, it would be cooler and more meaningful if the team provided rewards just as custom NFT avatars for the winning guilds.

This draws inspiration from other esports such as league of legends and dota, where the winning team gets custom skins.

I believe this would inspire from involvement in guild war events as guilds compete to leave their legacy in the pixel games and make it more meaningful than just a monetary prize.

This customized collection could then also be minted by the public and a portion of the mint cost can be given to the winning guild.
