There are some cards I found weird that they are on the list. So here is some analyze of the cards from scale 1-5 (5 means it should totally be in the list and 1 it doesn't belong to the list). I think neutral cards should be restricted easiest because every deck can include them easily. Now there are some cards on the list which never see play. Post your thoughts also.
Itinerant Scholar
This I don't get. Card is ok that you can undrain your domain and drain your opponents biggest domain but it is one use only. I don't find that too major. Is there some recursion combo I am not aware? Was Misk rush too powerful before? 1/5
Things in the Ground
This is a cool card and could make some strong decks. But I don't see it needing restriction so bad. Maybe there is again some not Yog decks where this card would be too strong but I don't see them. 2/5
Diseased Sewer Rats
Might go to almost every deck if unrestricted. With skill 0 this card would had been perfect. Still strong but not too strong. I feel should still stay in the list because I fear I would face this in every game otherwise. 3,5/5
Negotium Perambulans in Tenebris
Can kill some rush decks and other decks too. Very strong effect and that kind of effect shouldn't be accessible to every deck . 5/5
Descendant of Eibon
The original card goes to category "what the heck designers were thinking". Rare to see so unbalanced card design in any game. After errata more balanced but still even those icons with 3 cost with blank card text would be totally playable. 4,5/5
Nyarlathotep
Poor Nyarl never gets to a deck because other cards in the list are stronger. 4 cost is a lot and the gap between 3 and 4 is a biggest gap for me. I don't think this would be included in every deck if it wouldn't be in the list. Hard to say. 3/5
Guardian Pillar
Costs one too little. I like the card but it so hard to get rid of. At least only works during your or opponents turn and it is unique. Might be ok to unrestrict if there are more dreamlands cards coming and some location/support controlling cards. But should stay in the list for now. 3,5/5
Doppelgänger
Powerful character that I don't want to see every deck 3x with some other Yog cards. 4/5
Khopesh of the Abyss
Duh 5/5
Iniative of Huang Hun
Bounce shouldn't be so easily done and especially not repeatable. Should stay. 4/5
Then cards to think adding to list:
Snow Graves
This card goes to every deck. Can somebody share design behind this card? Was it made to counter Eibon? I haven't played this game so much so I don't know. Discard pile recursion can be very powerful but this card kills the not powerful effects also. If there is too strong recursion card, then restrict it. Snow Graves just kills the balanced and fun recursion cards also. 4/5
Temple of R'lyeh or Deep One Assault
Only if Cthulhu is too dominant. Destruction and sacificing shouldn't be easily repeatable with Temple. If my board is cleared or almost cleared with Khopesh Temple gets very scary. I have to play 2xChar and then Attachment if I want to play any Attachments. I would also like to see other strong Cthulhu card restricted so there would be choice between that and Khopesh. That is reason to include Deep One Assault. 3/5
