Mystery cards

After an official match, the prize roll can drop a sealed mystery card instead of coins, XP, or a known cosmetic.

Drop

Drop chance	12% when your equipment bag has a free cell
Pity	A sealed card after 10 match rewards in a row without one (bag still needs a free cell)
One card per match	Claiming the same match again gives the same card

Rarity is picked first among tiers that still have something you don't own (empty tiers drop out). Inside a tier the item is a fair roll.

Rarity	Weight
Common	50%
Uncommon	25%
Rare	15%
Epic	8%
Legendary	2%

The pool is paid and drop-only cosmetics you do not own. Free starters are out.

Open (once)

Method	What happens
Pay $1	Checkout locked to that card
Gift code	One-use DOOR-XXXX-XXXX-XXXX
Monthly freebie	One per calendar month
Sell	100 coins; the card is gone; the bag slot frees

There is no re-open. Unopened cards take a bag cell on Rankings / equipment. Match-over can show a sealed face.
