Again, are purple or green nymphs allowed in the deck building part?
Since the halfblood research is likely to help out newbies who won't have nymphs, building nymph decks is probably shooting yourself in the foot - unless you do it with Nymph's Tears.
In my deckbuilding portion, I plan to build unupped and rareless for newbies, but I'm assuming unupped isn't mandatory?
