I have on occasion found one in a deck, but I didn't put it there on purpose
There are many ways to exploit it along with Sword of the Meek that can go from taking infinite extra turns with the help of Time Sieve or add infinite mana with Ashnod's Altar, making it a solid card to include in artifact and combo decks overall
However, if you're a collector of the prettiest (or, potentially, the most expensive Pokmon cards), these could be a worthy buy
Fortunately, players start with 40 life and black provides access to spells like [card]Exsanguinate[/card] that refill your life total, so paying one per card usually isnt too painful
Box structure: 20 packs per box 7 cards per pack 1 guaranteed SR or better per box Higher overall pull rates than standard sets Typical hit rates: 1 SR or SAR (guaranteed) 34 Double Rares (ex cards) 1012 Holo Rares Multiple packs containing reverse holos These sets are known for their high entertainment value each pack feels more rewarding, and the card lineup often focuses on nostalgia or special mechanics (like Kanto Pokmon in 151 or Terastal ex Pokmon in White Flare )
When it happens, you just have to be in the market and own some good cards
