1) Yes, I was thinking of the Semi-Limited Notice policy. I usually put a lot of cards at 2 anyways for balance reasons, so it is easy to get a lot back here, but it is not too bad. The run I had before commenting I got it and also the policy that gives assets when playing limited or semi-limited cards in battle, which was extremely good but probably should be and even having the option to take that meant I had already gotten pretty lucky.
2) Yeah, I misunderstood the eye-markings to have appeared because I took a pack that needed no other Earth packs or something like that and I was wondering why it only appeared over the one mixed pack rather than both. Now that I understand, it is a cool mechanic but I also think a visual indicator for packs that will break conditions would be neat.
3) You are probably right about the old Normal mechanics. I imagine this plan is a good change, but you should probably change the dialogue that comments on Normal not really working with other elements and maybe being a bit too separate that one of the characters has a chance to give when considering normal packs.
4) I forgot mixed counts as all types even when not in the graveyard; with the new aura mechanics that makes sense. By the way, the new coin system makes mill decks a lot less powerful, which is probably a good thing (the AI used to mill itself out quite quickly by playing coins if you let it, and I imagine it still would).
