True, that was all worst case scenarios. Garchomp is actualy an even matchup, but the reason I favor it more is the fact that the stage 1 is easier to get out than our stage 2. Empoleons built in draw-power only works if you have the stage 2 out, and is gone once he is killed. Gabite, on the other hand, can just sit on the bench providing suppport until either you get a catcher (and then get hit by the Garchomp) or KO the Garchomp, in which case the Gabite comes up and evolves.
Also, you would not run Giant Cape, you would run Rescue Scarf it is in general a better card, even if it allows Hydreigon to kill you, it is better in more matchups.
