C'Thun does a few things that are at least a bit interesting. It's like a mini Archivist Elysiana if we ever get people worried about control mirrors. (Right now control decks can't beat Tiktakus, though). All the cards it adds to your deck are on average better than Archivist Elysiana cards too.

And it creates a bunch of 5 mana spells, when there's some noteworthy cards that activate off of 5 mana spells like Groundskeeper, Garden Gnome, Anubisath Defender. Don't even need to play the spells for some of those; just have em in hand, which is good cause you're usually not in a rush to play these. Also the majority of corrupt cards are 4 mana or less, so 5 mana spells are decent corrupt activators.

Also, if I'm not mistaken since they are added to your deck at start of game, that means none of them will be in your opening mulligan, or be one of the cards you get back from your mulligan. This is actually kind-of important; normally 5 mana cards are bad because you don't want to draw them on turn 1, 2, 3, or 4. You're much less likely to draw these on early turns, which is a substantial advantage over other 5 mana cards with the same text. Like...C'Thun assassinate is much better than vanilla assassinate, just because you can't get it in your opening mulligan. If you draw it later in the game that's fine, you actually have the mana to cast it. The 10 mana C'Thun also never shows up in your mulligan, so no concerns there either.

The meta kind-of needs to chill out a little before an Archivist Elysiana style card will do much, though.
