So I've been saving up for the Re:Zero collab since July (I spent 1 ten pull for both summer Aya and any of the festival HaroHapi cards, I did get the Misaki.) I currently have 20k stars saved up for literally any of the collab cards. If I get at least one of the 4 stars or the Ako I will probably scream, cause I love Re:Zero and I'm currently watching the 2nd season. I had no luck with getting the two 4 stars of the Persona collab (Thankfully I got Moca)and on JP I had no luck with collab Arisa or collab Hagumi/Kokoro (I got Misaki).
I also hope to have some stars left over for HaroHapi Christmas cause I love that set I want Misaki or Kaoru, but Hagumi would be aight too.
So basically on EN I'm trying to save up for any cards I like and the next one I'll probably save for is Pasupare Valentines Day or Backstage Pass 3.
On JP I'm saving for the Christmas set this year which I'm hoping is either mixed or RAS cause their the only one that can probably have the event cause Popipa, Afterglow, and HaroHapi have had Christmas events, Roselia and Pasupare had limited holiday events already, and Morfonica had an event recently. Also RAS needs more cards.
