Dreamquest was the original roguelike deck builder, and it had a lot of depth that you wouldn’t expect from its shitty art, I think it’s still worth playing. One of those games that seems extremely difficult until you learn the strategy, it is amazingly well balanced, small mistakes are the difference between win and loss
SpellRogue was fun for a bit but not sure it has staying power the way StS does.
220TB in 10 years on a 250GB disk means you are doing the equivalent of rewriting the entire disk every 4 days or so for 10 years
