Saving up Script space via merging is one of the known techniques in MoonKarts. Rarities play important role towards a better rewards economy and Orbital rewards. In the thrilling world of Moon Karts, every racing advantage starts with the cards in your deck. These aren’t just collectibles—they’re your performance boosters on the track. Every playable asset—from drivers to karts and power‑ups—is represented by a card, and each one fits into a tiered system of four rarities: Common, Rare, Epic, and Legendary. You'll find them neatly organized under the “My Cards” section in the game.

Common Cards are the workhorses of your starting lineup—easy to come by, solid for early gameplay, but they offer only baseline stats. Step up to Rare Cards and things get more interesting: these provide improved stats or abilities and demand a bit more effort to obtain—think achieving wins in advanced races or unlocking them via higher‑tier packs . Epic Cards go even further, offering game‑changing abilities that truly elevate gameplay, though they’re harder to come by—earned by completing tough challenges or special events. And then there’s the top tier: Legendary Cards. Powerful, prestigious, and exceedingly rare, these are reserved for players who conquer the game's toughest feats or reach the highest echelons of competitive play.

But rarity is just one part of the equation. Moon Karts embraces a dynamic leveling system known as Merging—inspired by Splinterlands—where you combine multiple cards to level them up, evolve them, or even unlock new powers. This process is universal: all cards, regardless of rarity, can be merged to improve performance—and better cards translate to higher earnings in races. Plus, the game includes a dazzling twist: Gold Foil Cards—much rarer versions of any card that deliver bonus rewards and require fewer copies to merge. The best part? You might get a Gold Foil any time you open a pack, and stacking them can multiply your advantage
In essence, mastering Moon Karts isn't just about picking the right car or driver—it’s about smart investments in your deck. Knowing the rarities, using merging wisely, and hunting for Gold Foils can give racers a decisive edge, both on the track and in earnings.
