trap card in the current format (and oftentimes the only trap card many players will feature in their Main Deck) is Infinite Impermanence
If I didnt know the release date of Japans Expedition Base Set Id assume that these packs were for sale around October 2001 instead (likewise those 3 sticker packs above could very well predate the March 2001 sticker set, but this fortunately doesnt happen often so its somewhat unlikely)
As the name suggests, these cards feature a gold-patterned background
Their new Field Spell lets you send 3 cards to the Graveyard to Special Summon a Sacred Beast from your hand, Deck, Graveyard, or banishment, and make it immune to your opponents activated Spell & Trap effects, too
Otherwise, shes identical to the Yzma card weve already seen in terms of cost and stats (they can each gain two points of lore when questing, too), though shes an Emerald card rather than Amethyst
