Card Merging: Upgrading Your Cards.
All cards, regardless of rarity, can be leveled up to enhance their performance. Similar to Splinterlands, players can combine cards (referred to in Moon Karts as "Merging") to level up, evolve, and/or unlock additional abilities for their cards.
Upgrading cards allows players to continuously improve their gameplay strategies, adapt to different challenges, and stay competitive in the game. In addition, having more rare and higher level cards can contribute to earning more in any given race.
A full overview of the card merging economics and performance modifiers will be unveiled closer to launch.
Gold Foil Cards
Similar to Splinterlands, all cards in Moon Karts are available in a much more scarce Gold Foil version that offers bonuses when playing and for which fewer cards are required to level up. The reward bonus from gold foil cards is stacked. So you can have multiple gold foil cards applied to your kart to maximize the reward.
When you open a pack, every card has a chance to turn into a gold foil card.
