I wouldn't use the card set on a Genetic, or any other class specific card set -- they're so underwhelming compared to other cards you could use.
They (the card sets) worked well enough on pre-renewal, example the Crusader set was a great alternative for Grand Cross builds.
The old Purple Boxes you seek have a drop rate so infintesimally low that you will soon lose interest in it, perhaps like I did.
It can be fun to slap on some carded equipment that have you drop fun little things when defeating mobs, but I think that's mainly a novelty thing.
Spare Cards are interesting, but I will just leave this here and wish you luck in your carding endeavor
N.B.:Part of my response is for your other thread which pertains to the Merchant card set you spoke of here, as well.
