Garchomp is pretty good now. Claydol gave it the consistency it needed, and it top cut at Worlds last year. After the MD on rotation, Claydol was rotated, so it had some late game problems, even with a heavy Uxie line. But I feel plain Garchomp with maybe 1-1 Lux X and some Lost Removers will make it a good deck.
Also, when BW comes, this'll be one of the best decks to play IMO. (Pokemon Catcher and Crash Hammer)
If you're not playing them for states, keep them for when BW comes. You wont regret it.
