Got Mortuus same day I got both luck gamepasses!
I managed to get a Mortuus on the same day I got the Lucky and Super Lucky by sheer luck! Didn't expect to get it so quicky, this is my first Mythical Pet! I've got like four Immortuoses because it's a 23% chance to get them from Tier 12's. Going to try to farm Tier 10's for the Dominus.
