There are four different card rarities: Common (bronze), UnCommon (silver), Rare (gold), and Ultra-Rare (diamond). In Skylords Reborn, promo cards are considered a special rarity above Ultra Rare, with a low chance to drop from boosters. This is unlike BattleForge where all promo cards were given out for special occasions. Below is a list how the respective rarity icons look like:
