It's been doing this since 2011, when you could enter a code found on a card to get another booster pack in Pokemon TCG Online
These include: Age (or when the card was first released) Rarity (or how likely it was to get the card via its official release, and how many copies exist in total) Condition (or how well the original physical attributes of the card remain, absence of scratches to whitening to creases, bad centering, and/or other deformities, to name a few) Price (or how much currency is being asked by the seller, including shipping fees, platform fees, and tolls/customs) Availability/Scarcity (or how many copies of the card are currently available on the secondary markets for purchase at any given moment) Popularity (or how much demand exists from other people that also want the card, for whatever reason, which may be short-term hype/FOMO or long-term fundamentals) However, these are not all equal metrics
This legendary Elf Noble from the K aldheim Commander set will now be legal in Standard, Pioneer, and Modern for the first time
If you put no cards into your hand this way, put a +1/+1 counter on Nashi
