You know what I was really really expecting to see come out of Innsmouth, a higher level dark ritual with one change.
"...Spend 1 resource or release 1 curse sealed here.
If there are no tokens sealed on dark ritual discard it."
The main issue with curses is having a lot of them around all at once, if you only have 2 curses about they are nowhere near as deadly and a single false covenant can easily just siphon them out of the bag, having a card that turns a large dumping of them into a slow drip feed would have been really useful, but I guess favor of the moon does that a lot better.
Given how much curse erasing exists just in survivor I don't see why you would run Dark Ritual for that, the biggest and best rogue curse card is Faustian bargain, it seems a little silly to use that and then follow it up with a resource sink.
Using dark ritual for short bursts seems to be the only use case it has, when you have a turn or two where failure can't be tolerated you can throw it down and spend the 2/3 resource cost to keep curses at bay, but even then at level 0 this card still looks poor compared to what tides of fate can do.
I'm trying my hardest to think if there's a reason you'd want curses sealed for the sake of it, like with guardian cards that can grab sealed blesses but I can't think of anything, I like to think every card has some amazing power if used well but for now I concede to Dark ritual.
Its coffin was carved by False covenant and buried with Favor of the moon. I hope like with all cards one day I will see where its power lies, every card is amazing in the right place, this one is probably going to need to see return to Innsmouth before that place arrives.
