Oh, I looove all these previews!!!
You can compare this to Stables.
$X ---(x1)--> +3 Cards
$X ---(x3)--> +X+1 Cards
Plus the money from Action cards (which can be both good or bad...)
With this, Magpie, and Hero, maybe there is a Treasure theme?
I think you have to be careful with the Stables comparison, because as was pointed out above, Stables discards (and can therefore redraw), while this plays the Treasure, so it cannot draw it.
I think the bigger problem with the comparison is that with this, if you only discard copper, you aren't ever increasing your hand-size; the same is not true of Stables. Also, this is never dead (though you may not want to play it), whereas Stables can be.
That, namely, is to turn cash into cards. Coppers turn into cantrips, Silvers turn into labs, and Golds turn into double labs, and all on a card which. This is, in general, an improvement in every case. And all of this is on a card which is a cantrip by itself.
Some extraneous words there.
I know that it isn't the main point of the card, but I like that this is another way to get treasures in play during the action phase. Completely agree with WW about that.
:/ I apparently missed an issue whilst editing... which I am sure I introduced in editing. Thanks for pointing this out, should be fixed now.
As for the "do I want treasures" kind of questions - I think pretty clearly this card isn't very good without treasures in your deck. It's just a cantrip mostly. Sure, you can construct scenarios where you are playing coin-producing cantrips and want this to play after to draw with, but I am guessing that's really rare. It feels like it would be rare, anyway.
