what do code cards do in pokemon Card - 151 Booster Pack - SV: Scarlet & Violet 151 200 Booster Pack Code Pokemon

Elven Chorus I prefer Elven Chorus to most other forms of green card advantage, like Guardian Project or Beast Whisperer

7 Crown Zenith Ditto (Numel) This card has one Ditto disguised as the third-generation Fire-type Pokemon Numel, blending into a herd of them

Furthermore, there are many more widely played formats (such as Tiny Leaders) I could provide a link to, but the reality is that if you include all those formats in your definition of previously banned, some person will eventually just invent a format that bans every card but basic lands, and therefore will be able to tutor all cards

The reason its not in the Top 10: its a contest promo, not a booster or high-class pack card
