Hi there! I am the Guildmaster of Illusions of the Grave. You can earn DEC bonuses per battle and discounts in the Splinterlands store based on your guild lodge level. You can also enter brawls to earn merits to use in the guild store where you can buy gladiator cases (card packs). These cards can only be used in brawls. The game devs are considering adding sps as a reward for brawls in the future (I estimate once the airdrop ends but don't quote me!) Best of all though- guilds are a community where you can ask and answer questions without judgement. Plus sometimes guilds run contests like these to encourage participation and bonding. I hope I answered your question well!
