For the sake of balance, every element should have a rare other than the nymph. That being said, the game is not really balanced. Death has 16 bazaar cards now and 1 nymph. Certainly it deserves no other card now.
I would prefer it, if the rare was not, like impossible to obtain. The squid and the pharaoh are decent rares. Neptune and Osiris pack them in bulk, so there is at least the chance to win them. I can say the same for Akebono/overdrive.
The vampire stiletto/dagger was always an absolutely useless rare. I think it is in ai3 now. Before that, getting it off an FG was near impossible. I won maybe 1 or 2 and I beat the death/dark gods often.
So I'm not against it, IF the opponent is packing a decent amount in the deck. Getting a warden of an ai5 is just murder..
