Balance Thread

I'll side with masa's more conservative suggestions on Target the Engines (2/1 cost, Allying 2 or 3, target gens of cost 2 or less).  And while you can certainly get Allying 2 by turn 2 easily, it's not so easy to get Allying 2 and cast a 2/1 spell same turn (not impossible, but not especially trivial, either).

Overheard Information also struck me as a pretty nifty decking card, but unlike Eureka/ToK, it's really only useful if you're trying to deck your opponent.  So I could get behind 45 or something like that, but I don't think I'd go any higher.

Oh, and I think Sword Dancer should just be cheaper, like 3/3.  I think it compares fairly reasonably with something like Skelebird, once you remove the entrenching factor.  Frankly, I think I'd still rather have Mechahawk (but that's probably a little too strong too... maybe 42/50 instead, with reduced (43) sac?)
