some splash gold might be good to consider as well. the generous widow is valuable with gifts of the magi, which nets you 8 cards total in a normal multiplayer game. repentance and restitution is almost auto-win with her low numbers (and if you dont mind your opponent drawing 4 cards), and convincing miracle is useful for thinning your own deck and against other speed players.
which begs the question, are we allowed to count the number of cards in an opponents deck?
Hmm, never thought about that. But Generous Widow would be the only gold card to splash in. I have enough battle winners, considering the lack of defense in multi is so vast.
And I would assume you could ask your opponent to count how many cards are left in his deck. Considering you can ask the number of cards in their hand. Since both have consequences on cards now.
