From what I can see in my collection, it is Want List only. I am still able to add all the cards in sets into my Collection without any issues.
Question that comes to mind, why would anyone want 1M cards on their want list? Nothing like a focussed collection. Of course I know one who has everything on his want list as it helps attract PIF coming his way.
