i was just scanning the quantities of common cards ytd, as i observed/noticed - most of the earlier sets (even rerolled as much as they were) hv abt/at least 5~8 cards currently, while some were up to 22(i forgot which or how many). i think i prefer my faves to be popular, as i always shiver when one is rerolled/rouletted (n removed by roulette rules, i mean). i predict tat in the roulette , least common card added might be at least 6~10 in quantity starting soon if not now. maybe i shd hv suggested my idea for tweaking the roulette earlier(i thot of it when i skimmed the cards added/removed in last roulette).
tldr: i prefer my faves' cards to be popular-mostly. hey its not like i hv any control over who my faves are/how many users like the same cards. tat said i been lucky to get most/many of my faves' cards. bless the cards gods/algorithm/users who traded with me.
