Rainbow Rares are gone, with the new Secret Rares consisting of Full Arts (yes, Full Arts are now considered Secret Rares for the first time), Illustration Rares, Special Illustration Rares, Gold cards, and more

went back and forth on my choices multiple times xD But ended up going with this: #3 My TrainerSona's team, based on some of my favorite Pokmon whose real-life equivalents or close I've encountered (see spoiler): Frosmoth sprite by leParagon I also swapped Badges out for treasures since I doubt I'd participate in any leagues, the Leaf Stone representing all the plant fossils around here (I've been tempted to evolve Eevee into Leafeon because of this) and Root Fossil a crinoid stalk I found in some gravel
