And it shouldn't be more "wtf" to newer players than Chancellor is.
well chancellor probably shouldn't exist either, at least not in the base set.
It wouldn't be pointless, it would be incredibly useful
you really think so? I think it would be useful in a minority of games. there is also no other card which + is only information.
In games with reactions, attacks, or a close endgame, you would benefit from knowing your opponents hand. I think that includes most games.
the thing is, even if that stuff is there, it's still unlikely that this kind of information helps you. even if your opponent has moat in his hand, you still want to play militia, because it has +2$. the moments where it's better not to play an attack are rather rare. like, if your opponent has draw to x in his hand and you don't need the $, or if you play another terminal silver with a better bonus instead.
and it might even be political, one player has library in his hand, the other one doesn't. do you play your militia now?
don't get me wrong, I would like that card if it existed. But I don't think it should exist.
