Every card on TwinCard is a real card from sealed displays we opened. This page shows what is left in our stock, and how every draw is calculated so you can check it.
Cards left in the boosters
These are the real cards still waiting in our stock, updated live. Every card you pull is a real card from our displays.
| Rarity | Cards left | Status |

Drop rates never change. Within a rarity, every card in stock has the same chance. A card that runs out can't be pulled until it's back in stock. If a whole rarity runs out, boosters are paused until the next restock.
Provably fair draws
Each draw is calculated from three values, so the result is fixed before you click and can't be changed afterwards:
- Server seed: a secret value chosen by TwinCard. We show you its hash (a SHA-256 fingerprint) in advance: it proves the seed can't be swapped later, without revealing it.
- Client seed: a value linked to your account, mixed with the server seed.
- Nonce: the number of the draw, +1 each time. You can find it in your draw history.
Every card of a draw comes from an HMAC-SHA256 of these values. The number obtained picks the rarity (with the rates of the Drop rates page), then the card among those in stock.
Coming soon: choose your own client seed, reveal your past server seeds and check any draw yourself with our verification tool.
Fairness report Coming soon
Once enough draws have been made, this section will compare what was really pulled on TwinCard with the announced drop rates.
