Every card lands with a seal — Normal, Rare, Unique, Epic, or Legendary. It looks like a game. The grading underneath is anything but.
Behind every card is a score from 0 to 100, earned during its evolution run — a weighted read of how strongly it performed: profit factor, win rate, growth, drawdown, and how actively it trades, discounted when the sample of trades is thin. The seal is simply the band that score falls into:
Normal (gray) — below 67. · Rare (blue) — 67 to 72. · Unique (green) — 73 to 77. · Epic (purple) — 78 to 83. · Legendary (gold) — 84 and above.
Higher tiers are rarer for the honest reason: fewer strategies score that high and survive the gates intact.
The seal spins like a roulette when the card is revealed — that part is theater. The grade itself is deterministic: the same card carries the same seal every single time, because the score was earned in testing, not drawn from a hat. There are no odds to sweeten and nothing to buy that changes a grade.
That's the line CoinLAB tries to walk: the fun of a card game, with none of its dishonesty.
Treat rarity as a first-glance filter, not a final answer. A higher seal means a stronger score — but the report tells you how it was earned. A Legendary running 5× leverage can still swing violently on the way to its return; a quiet Unique might be far easier to live with. Open the card, check the drawdown and the trade count, and judge the whole animal.
And remember what's being graded: the past. Rarity ranks how convincingly a strategy survived history — it makes no promise about next month.
Rarity grades hypothetical performance on past data. A high tier is not a prediction and not financial advice. Always do your own research.
