I only played one round of Survival mode so far, and thankfully I won because I don't have a good deck for it! :D

Looking forward to campaign mode.

How much info out is there on this so far?

Combination to rewards more players with HP is a something worth to consider...

To stop it getting completely gamed, perhaps there should be some kind of ratio with SPS holdings also. So, someone has to be invested into both in order to benefit. Those with a lot of SPS might want to buy some HIVE to get some prints, those with Hive might want to buy some SPS.
