Has anyone put something like this together? New player, and may have to prioritize purchases at this point, due to limited "in the wild" stock.

Would also be useful in general newbie deck-building!

The current offerings I'm able to find, in terms of deck building tips, are limited and don't factor in specific cards, but rather seem oriented towards CCG newbies.

Looking at a variety of online deck lists, just to see what cards keep popping up, but have no idea about the builders' pedigrees...

You might try cardgamedb -- there's a feature to leave comments on individual cards.

Severn Gamaing Network does card spotlights and deckbuilding 101s:

There are more out there but these are a good starting point.
