27 of the cards in the OP are actually alright and I've seen them played to good effect since the midwinter patch. Some of them I see fairly regularly (Saskia, Renew, Letho, Regis, Succubus, Letho Kingslayer, regular Yennefer, Cerys, Seltkirk, Shilard) ... so I'm not sure why they're on the list at all. There are a bunch of other ones that work situationally pretty well that I see rarely, but do get played.
That still leaves 17 that I agree on, namely:
Sihil, Wolfsbane, Kambi, A: Sage, Pricsilla, Vernon Roche, Ciri not nova, Gaunter, Lambert, Zoltan Duda, Dandelion, Dragonfire, Aguara true form, Vabiorn, Old speartip ver 2, Xarthisius, Lugos. These need some work IMO, as I haven't seen any of them more than once in ranked.
