And its also a nostalgia trip for those of us who were there
While TCG Online players won't be able to use their custom decks in the Trainer Challenge mode, the workaround is using them in the test mode
That said, forcing some bad combat choices with first strike is also possible, so while Im not high on the card, its not a bad card by any means
UR Ultra Rare Animadorned Archosaur X LIGHT Level 1 [ DinosaurEffect ] ATK 0 DEF 0 If this card is Normal or Special Summoned: You can destroy 1 Dinosaur monster in your hand or face-up field, except "Animadorned Archosaur", then add 1 Reptile, Sea Serpent, or Winged Beast monster with the same original Level as that destroyed monster, OR 1 "Evolution Pill" Spell, from your Deck to your hand
TAHK0 speculated on why the error may have happened, writing, Poke Balls went through a lot of early variations, with everything from the button placement changing, to how it opens differing, to even being depicted with the white on top. It could be that an early Pok Ball design actually did open like it does on the card back, but when the design was eventually changed to the opposite way, they forgot to update it on the card back before going to print, and it remains that way to this day
