I expected to see Catapult right now and was set to argue that maybe it should be a bit higher. But since we haven't seen it yet, clearly it's being overrated.
Catapult, it's really bad. If you trash a copper, it's like a Militia that doesn't give you money. If you trash an estate, it's like a Trade Route without buy. Later you can trash good cards to curse your opponent, but that hurts your own deck almost as much as your opponent's. I mean, if you can spend an action to trash a $3, then your opponent can spend an action to trash their curse, and it comes out about the same for both of you, only you lost a $3.
In the previews, people were saying Catapult looks great, Rocks looks awful. It's quite the opposite. Rocks is the main saving grace of Catapult. In our group, as we've explored the strategy-space of Catapult, it seems the best thing you can do is buy ALL the Catapults, and then trash Catapults and Rocks to curse your opponents. The opposing player has to decide between buying a catapult (which accelerates towards Rocks, and is a terrible card) and not buying a catapult (possibly losing access to the only junker and trasher).
