How the Card System Works
Cards drop from card packs with varying rarities determining their drop chances. Legendary cards boast drop rates below 1%, making them incredibly rare. All cards start at Tier I, but you can merge three identical cards at the Card Merging station to upgrade tiers and enhance their effects.
Card Slots: You unlock five card slots progressively through Rebirth levels, with all slots available at Rebirth 5. Strategic slot management becomes crucial—choosing which cards to equip can make or break your efficiency.
Important: Card effects stack with weather event bonuses and potions, creating multiplicative power spikes when timed correctly.

Frequently Asked Questions
Q1: Can I merge cards of different tiers in Plants Vs Brainrots?
No, you cannot merge cards of different tiers currently. To upgrade a card, you must possess three identical cards of the exact same tier. For example, you need three Tier I Secret Collection cards to create one Tier II Secret Collection card. This merging system encourages strategic collection management and makes higher-tier versions of rare cards extremely valuable.
Q2: Do card effects stack with potions and weather events in Plants Vs Brainrots?
Yes! Card effects stack multiplicatively with bonuses from weather events and potions, creating powerful synergies. For example, using an Overgrowth card (+50% luck) during a lucky weather event while a luck potion is active can create massive spawn rate increases for rare brainrots. Smart players time their card loadouts with in-game events to maximize efficiency and collection rates.
