About card that should be nerfed

I understand that many people want to buff powercreeped cards and it's good idea. But i think also that some card must immediately be nerfed in order to better the game balance. I made a list of cards, that in my opinion should be weakend

• Sir Scratch a lot – unanswered can make a several dozen points. I would give him a counter to replay him or take him that passive ability with activate thrive by enemy units.
• Witches Sabbath – imo unhealthy card that allow you for all this nonsense like triple gerni or kelly
• Imperial Practitioner – no need to explain, maybe card that practicioner can spawn should be limited by provision
• Simlas – he is definitely too strong but honestly i'm still not sure how to nerf him. Maybe give him less provision but restrict him to play only two copies of card? I will read your idead gladly
• Saskia Commander – this card is strong red coin abuse, which often leads to win r1.
• Deranged Corsair – still to strong for 5 prov in my opinion

There are also definitely other changes, which should be done in my opinion. Things like cultists or knights are too strong for other archetypes like symbiosis for example, which can't compete against them. And what is your opinion on actual meta? What would you change?
