24 Sphinxes is 5 runs of the Black Hole stage, which costs 14 keys and 10 stamina per run. That's a total of 70 keys and 50 stamina, and 1 of those Sphinxes is wasted.

Equivalently, it's 2 Harpies for any other card. That means 2 runs of the 100 keys and 30 stamina stage, or 200 keys and 60 stamina. That's worth a lot more.
