Well, it's actually pretty good. The first attack basically equals an instant KO for most Basics, which is pretty good for 2 Energy. The second attack giving a freebie 100 damage for 20-self and one more energy is even better, making an instant KO on most Stage 1s. The self-damage isn't that bad, either, considering Rampardos' high HP. Of course, the attacks for a Stage 2 are expected to be high, but with all the ways to bring Cranidos out immediately that will undoubtedly exist, this card is actually a Stage 1 in practice. The bottom line isn't that bad, either, for a fossil Pokemon.
9/10 until those methods are revealed.
