Taru Death CardFollow

Is the card quest totally random or is there some sort of logic to it? My LS has several people leveling BLM and they are getting ready to hit the dreaded Sleepga II quest and guess what? Most of them threw away their Taru cards way back in the long ago. So a bunch of us, banded together, bought much moss and escorted many mules to selbina to stuff sheep full of corn and moss. We took them to jueno and now have 40+ hermit sards, 35+ king cards, 25+ Fool cards and 0 death cards. We have traded with all race/sex combinations except male taru getting cards and only lack (I think) trading in on Lightningsday to have traded in on each day of the week.

Am I missing something or does anyone on Levithan have 5 of these cards sitting in storage somewhere?
