A. Darkrai outclasses CMT on many many grounds. B. Rayquaza is a horrible card, it takes too much to set him up (energy-wise) and he does the same damage that Zekrom does, but gives up two prizes to Garchomp, which can OHKO Ray on T2. Also, if your Fire Energy gets discarded, you're done, that's it no more Rayquaza, now he's a free two prizes.
