How It Works

A seed bank you can play with. Real seeds ride inside every card, and the game is built to reward growing and saving more of them.

Current status: in early development.
The first card set, the seed library, and the public TerraDex are being assembled. Nothing is for sale yet, and no seed packs are shipping.

The card is a seed case

Every card is a small, sealed case that holds real seeds of one species. The front carries the creature art for that plant; the back carries its growing and storage instructions. A window in the card shows the seeds themselves, so the card doubles as its own proof.

Seed fullness sets the level. A fuller, fresher case is a higher-level creature. A depleted case is a lower-level one.
Growing difficulty sets the rarity. A plant that is hard to bring to viable seed is a rarer card than one that self-sows freely.
Saving seed is how you mint more. Surplus seed you grow and clean can be verified and sealed into new cards.

From seed to sealed card

Contributed and grown-out seed moves through a consistent pipeline before it becomes a card:

Received seed is identified by kind and variety, then tested for cleanliness and germination.
Off-type, damaged, or non-viable seed is removed rather than sold.
Each lot is labeled with its species, origin, a germination result and test date, and expected storage life.
Verified seed is sealed into a case; the seal is signed and dated when a card is set for battle or its registry is updated.

Playing grows real plants

Battles raise a creature's power tier, but the currency underneath the game is planted seed. When you lose, the cost is an amount of seed you commit to actually plant. You can also sacrifice batches of your saved seed to tier a creature up. Every path forward in the game is a path that puts more seed in the ground.

Right seed, right place

Donated seed is matched to the region and season where it is most likely to thrive, so genetics flow to where they will actually grow instead of sitting on a shelf. An open archive keeps varieties alive for biodiversity and for emergencies, so a variety is never one bad year away from being lost.

Compliance is a by-product, not an afterthought. Truthful seed labeling asks for exactly the data the game already needs — kind and variety, purity, a germination percentage with its test date, and who handled the lot. Because the TerraDex records all of it anyway, honest labeling falls out of playing the game correctly.

The physical product, in stages

Printed paper envelope. The first format: a seed envelope printed with the creature and its full label, usable as the card face.
Sealed hard case. Envelopes move into a rigid, resealable case with a viewing window for the seeds.
Signed & dated seal. Tamper-evident tape is signed and dated to set a case for battle or to update its registry, so a card's state is verifiable at a glance.
