+
+2 bad cards = 1 ok card
+3 ok cards = 1 good card
+4 good cards = 1 great card
+5 great cards = 1 epic card
+
+Shiny cards can only be dropped with 0.5% chance or upgraded using a store purchased item
+
+## Entity relations and stuff
+Single card of any character  
+belongs to a band/group  
+which could be part of their topmost genre (?)  
+
+Completed bands reward cosmetics and XP (scaled to band size)
+
+Band levels by collecting duplicates (?) as a long term hook
+

+
+### archievements as profile badges  
+- [50, 100, 500, 1000, 10k] Cards collected  
+- [100k, 500k, 1m] Notes spent total

+   - players with low funds (notes) could be targeted by high item discounts with a higher chance of conversion   
+

+
+- [7d,1m,6m,1y] Daily streak
+   - ties in to the social feed to apply pressure to friends to keep up
+
+- [10,50,100] Shinies present in collection
+- [5k, 10k, 100k] Bad/ok/good cards in collection (each q level separately)
+   - Discourage converting cards to currency, purchase instead
