What should I be doubling up on, and what should get the axe?

Forum member Darksbane put in some great work and published sample decklists with cards from two core sets. Be sure to let him know if this was helpful to you.

Excellent, that's almost exactly what I'm looking for. I wish there was a bit more of a process to read about, but the finished work is a great tool to have as well. I figure the process will be rather self evident after a few games with the individual Precon decks.
