I am just speculating, but (a) 10-star requires 9*15=135 dups, which at 10 dups per month would take over a year on average to complete. (b) developers seem to be preparing more arcane cards to collect - see Blade of Sunrise #712 in the Table of cards. So, I think there are still plenty of discord guild owners looking for dups, but I also think it won't last forever.
