A unique gift box
Secret Rare cards were removed from Booster Packs starting with Soul of the Duelist , and were not reintroduced until Strike of Neos
Not every deck that can run Kricketune will run it, but decks that do will likely include 2 copies of the card, in addition to 2 copies of Kricketot, the Basic Pokmon
The value of X is determined only once, as Strength Bobblehead's last ability resolves
Simply put, its easy for collectors/lay buyers to accurately price a single card given the sources mentioned earlier (TCGplayer, eBay, PSA, etc.)
