I thought the Deck Builder Bundle at HumbleBundle was pretty good.
This blows that out of the water!

Dicey Dungeons is really excellent.

Of these deck building games, which ones might have interesting text descriptions for each card? The way Magic had suggestive texts. Checking the titles in the sale I found a review mentioning this for one of the titles, but I really cannot find it anymore.

Cultist Simulator.

(Not sure it's exactly a "deck building" game though. Doesn't play like Magic and stuff. But it hooks you like a novel.)

I don't understand why it got included. I'd argue that it's just a clicker with hard failure mechanics – nothing more in terms of gameplay.
