Very little detail was put into the story about the location, so not much was known about it
But it definitely makes more sense the way you have it
Normal Deck 6.2 16 [22529] JP166 Arsenal Summoner Effect Monster Flip Monster - 4 Spellcaster 1600 1600 FLIP: Add 1 "Guardian" card from your Deck to your hand, except "Celtic Guardian", "Winged Dragon, Guardian of the Fortress #1", "Winged Dragon, Guardian of the Fortress #2", "Guardian of the Labyrinth", or "The Reliable Guardian"
"Magikey Mechmusket - Batosbuster" and "Cyberse Sage" are the only Tuner Ritual Monsters
So to have another shot at that rare card, you have to reset the box, thereby flooding the pool with a fresh stock of duplicate garbage
Preventing any non-Eye creature from attacking, both of these cards are oddly perfect for us
