How it works. Cards sit on a five-rung ladder: Level I (Common), II (Uncommon), III (Rare), IV (Prestige), V (Legendary). Empty slots take Level I only. Any card may instead be played face down as a rock: uncapturable, counts as Level I, one per player at a time. Upgrade a slot you control by playing exactly one Level above it; it captures like a fresh play. Higher touching number wins, ties hold. The game ends the moment the ninth slot is filled.
