I don't mind the indices that much.
As a longtime poker player, though, what I won't do is play with a dark deck of almost any design, and certainly not these. The Jc and Qs (and even the Kd!) above have almost no significant contrast, especially if you're on a racetrack table near one of the ends. There's no immediate recognition even checking your hole cards where the cards are purposefully in shadow.
I like the similar, but different styles from one deck to the other though, and I've always been a fan of the scarabaeidae family. I'm down for a pair.
