The bug seems to be when I use rarities on either A Legendary Ocean or Pacifis, the Phantasm City they turn into regular umi cards.
Replay of A legendary ocean not working as intended
Can’t use Warrior of Atlantis to search but can if a legendary ocean is common rarity, Kairyu shin unable to be normal summoned, levels are the same and don’t change under the field effect.
Replay of Pacifis not working as intended
Special summoned Giga Gagagigo with no prompt from pacifis to search, was able to summon electric jellyfish after which was unable to happen because pacifis would usually prevent it.
Both instances would resolve the same way in the case they are just an umi field spell. Maybe it has something to do with how they are always treated as umi, but it only happens when they are a different rarity.
When A Legendary Ocean is played the water cards in my hand and on field should be 1 level less. When Pacifis is played I should be able to summon a token when my opponent activates effects and if I summon a normal monster I should be able to search out a phantasm spiral card.
P.S. Sorry for posting again, it seemed as if the original post was brushed off. It’s not important as since it only effects them when using different rarities it can be avoided, but I wanted to at least put attention to it again.
