Yeah, this is a great addition! Older players can lotto for new starters to play or hope for 3*s, and more importantly new players get a great feeling of progression! In the past, it was so hard for new players to modify anything besides SS in their deck, because of the huge card pool of regular lotto. With this one, it is not unrealistic to get stuff like Fire Arrow, Return, Lethal Archer playset, Sorc Monk playset, etc.
One of the best parts is actually getting sideboard cards from the other starters (so Falkow newbies can get Eagle Soldier, which isn't in the original Falkow starter). If the pool is eventually expanded to include old starters, there will be even more opportunities to do this, while still maintaining a small enough pool to get playsets.
Anyways main point is, this is a great addition, probably the best thing for new players yet!
I really want to recommend this game to friends. I would feel much better about doing that if things were less expensive, like tens of dollars to get most of a set, instead of hundreds!
