Haha that's great to hear, enjoy! I've been lending these spare cards to my brother for a good while, but he hasn't been using them almost at all, so.. I think it's better that someone who plays regularly and actually is building a collection can use them.
Regarding the SPS, it actually doesn't cost me any. The delegator still gets the aidrop points. And no worries, I'll take them back if I need to ;)
