Collectibles are special items in MUT used to complete 'Sets'. Sets require a specific combination of player cards or other collectibles to unlock a high-value reward, often an elite player or a large coin sum. Pay attention to which collectibles are needed for current sets and strategize whether to sell them on the Auction House or use them for completion. Completing sets is a great way to acquire top-tier players without relying solely on pack luck. Always check the rewards before committing to a set.
