I've played a few games with this, but paying 2 for the event just to get the buy never left me with enough for the second card I wanted.
There's the Counting House super combo, but other than that I'm not sure how I should be using this.
Maybe you can use it on your opening turn to top-deck an Action for turn 2? Maybe you can get a trasher and have a small deck on the first shuffle?
Best use of this card is as a component for solving Dominion puzzles.Definitely. Combos with Quest.
