Junk Synchro Decks that specialise in the Dark Synchro Monsters could be very interesting as well. I like the idea of getting them working, and the new Dragon Structure Deck will provide exactly that level of umph to get it off the ground.
With TG and Agents nerfed, I'd be willing to bet they'll become new carrier archetypes for newer debuts to come in the next few months, particularly with the new set as well. It'll be a lot of cycling in and out of the Graveyard for a while, so don't expect Gravekeepers to fall off the map any time soon. In fact, if the TCG gets the Yuma Duelist Pack the way it's printed in the OCG, they'll be even more popular thanks to the "Wonder Wand" (possibly) Common reprint.
Anyway, that's my 2-bones worth for now.
