I can't seem to find the promo pack cards from Throne of Eldraine (the ones with a planeswalker symbol stamp). More specifically the cards listed as coming from a curated list do not appear to be in the database. I have opened
Castle Embereth
Lovestruck Beast // Heart's Desire
Mizzium Tank
Once Upon a Time
at well as Lotus Field which could also be found in the Core 2020 promo packs.
