Now with Arkham Horror Chapter 2 core box released, and especially its core campaign reward card "collector"(allowing you to add one relic or charm asset of any class level 0-3), this card seems valuable to Joe Diamond from the 1st edition as the pick for collector.
Why? this version of Joe Diamond has a 11-card side hunch deck and 10 out of those 11 cards are events! And each turn if you play one of those top-deck from hunch side deck you can add it under Crystallizer of Dreams, which in most cases is a win-win each and every turn.
How to get Crystallizer of Dreams out of your whole deck? Well Joe has the level 5 No Stone Unturned inside his hunch deck right? which tutors his entire deck for this relic.
Finished chapter 2 core set campaign and I for one am gonna use collector and try this combo for the next campaign "children of blood", and see how it goes.
