If Garchomp LVL. X comes out in English, then that Garchomp MIGHT see the light of day. Without Garchomp LVL. X the normal Garchomp is not worth the cost.
But as for something that Garchomp could combo with...Garchomp would not get it's power from itself, no...But, a Garchomp + Delcatty (EX) deck could be a killer, throw in Blaziken. Blaziken for energy spread, Delcatty for draw, Delcatty EX for a strong powerful attack when there are stockpiles of energy from your fallen Garchomp...And then there is Garchomp, with a ton of different types of energy on it to help its effect...Who knows, anything is possible. But I would not put too much money on Garchomp being very big.
