Alright, folks, it's done. All 24 of my decklists are now in the sidebar, and are up to date. I'll make a real effort to keep them updated as I make changes to my decks.
I have a deck for each color or color combination, aside from mono-White. I still have no idea what I want to do for White, nothing really inspires me. A friend of mine has recently build a "Keyword Tribal" deck with the new Odric at the helm and it's pretty impressive, but now it feels like if I built my own version it would just be the same deck, maybe with a slight boost in card quality. I don't really have anything unique to bring to the table there.
Either Thalia would be a different approach than the usual White Weenie or aggro approach, but would also be very similar to my recently-built Grand Arbiter deck.
Guess I'll just stick with the 24 decks I've got until that "Ah ha!" moment of inspiration hits me.
