I've pulled 3 rare cards and 1 limited for Twice out of 4,2 sets (ie 38 cards)

A rare epxerience for me
My numbers are a tad bigger cuz I was so early to the game and there were fewer cards.
ie taeyeon common i got jan 21 ie 2 months after teh game started and rare dec of 21 just after rares dropped.
Yoona common i got jan 21 on the very first free day lol. so 3 pulls in 2 months of them being released. the other 3 are limited cards that dropped during the first event.
Red velvet i only pulled Wendy rare and joy val. ( and the Yeri L which i a fine with burning my luck for :))
I & S sub unit i was luckier on.
The limited sets have got to be the hard ones for twice.
lol those first months i was pulling so many twice that traded for snsd /RV ect. I think i got Jihyo 5 times at least that first year. and that sana Halloween i have had so many times .. i have her again :)
I have only 5 twice cards i traded for. but it took me about 2 years to get the commons and just underthat for the rares.
at that its much better than BP i didnt complete bp rare until dec 23 when i was finshing up all the rares lol zero trades for bp C/R cards.
