So you pick sets of cards rather than individual cards for your deck. This is *at least to me* an interesting development. What concerns me though is that these 'sets' are tied in to specific objectives as well. I'm wondering if a time will come when sets are released from specific objectives. Otherwise it seems to me the deck building aspect of the game could be severely restricted. I guess it does force you to use new sets though if you want to try the new objectives.

There's not really a lot of information on this mechanic yet but if it is anything like "Star Trek: Fleet Battles" deck building mechanic then it is very restrictive.
