For the uninitiated, it means Secret Rare, a type of Pokemon card numbered beyond the (alleged) official number of cards in a given set
A pack of 12 randomized cards contains: 1 Foil card of random rarity, 2 Rare (or higher-rarity) cards, 3 Uncommon cards, and 6 Common cards
Were explicitly told that your chances of a borderless foil rare or mythic in those slots is 1.25%, which comes out to 1/80 per slot for a borderless foil of either rarity
Important: Note that a character cant sing on the first turn the character is played
This cards in a bit of a weird spot where initially, it feels like the higher power you play this card, the more valuable the payoff might be
If you're new to Japanese Pokmon cards, I bet that list was longer than you expected
