Most decks aim to have 1 or 2 Dr's, and the best possible cards they can have within that star section. For example I wouldn't build a deck with X clan (Half decking with another clan, Y) if X clan had poor 4 stars. However Y has better 4* so I would get some 2 + 3 from X clan + pack 4's and possibly a 2 in Y clan.
You also have to compare them to each other, the best 3 star in NM.
There's Crowen, Pan, Edwin, Cutey. Depending on what your deck needs, a life gapping card like Cutey would be useful. If your deck needs to have a solid card from NM that isn't prone to SoA Pan would be your option.
