yes, the trophy list. trophies that needs to be finished first before a certain feature of the game unlocks are highlighted red in the trophy list. hover your mouse over to see what that trophy unlocks like this one:
this particular trophy unlocks the store. Is there any trophy like this on the list?
EDIT: it seems that you haven't unlocked the my collection button, buy a basic booster it cost 159 feez (you get a free 159 feez after finishing the first trophy), this will unlock deck edit which will also give you a next quest(put a card on your deck) which unlocks your collection after that you can level up your characters. I got vital syphon and black chimera from the basic booster to bad I'm gonna delete that new account.
