Membership Card

Membership Card is an Uncommon relic in Slay the Spire 2 that heals 15 HP every 5 cards you add to your deck. This relic rewards active deck building by converting card acquisitions into significant healing, providing a steady stream of HP recovery as you grow your collection.

The 15 HP heal is substantial and triggers repeatedly throughout a run. Most players add 15-25 cards to their deck over the course of a game, meaning Membership Card can provide 45-75 total HP in healing. This is comparable to multiple Rest Site visits and significantly eases the HP management challenges that plague many runs.

Membership Card is strongest in runs where you are actively adding cards to your deck rather than skipping rewards. It pairs well with Orrery, which adds 5 cards at once and can trigger the heal immediately, and with Question Card, which gives you more card options to choose from. The relic has anti-synergy with highly selective deck-building strategies that skip most card rewards, and with Singing Bowl, which encourages gaining Max HP instead of cards. For players who build larger decks, Membership Card provides excellent sustained healing.
