Yeah, as each round is being put into question left and right -,-U
Anyway, the fave ones on my Team vary.
Ziz (Aerodactyl): Ziz is just fun to toss into battle and cut loose with a prehistoric ferocity. I always imagined predatory Pokemon to be nightmares in battle, and Ziz was voted most fun to battle back in 08.
Behemoth (Bastiodon): The Prehistoric Pokes from 4th Gen have what I consider to be Swiss-Army-Knifes of Pokemon. They can learn a variety of elemental moves, plus their own specialties make them nasty in the right hands.
Tarasque (Rampardos): Tarasque is also in that category, and I love the move set as it allows for some devastating combinations and moves to use. While it may have some general weaknesses, it can still put up one hellova fight.
Blade (Scyther): Saddly, while Scyther is one of my favorite Pokemon, tis moveset is still limited for something I've always imagined as the "Martial Arts Mantis." While Reversal and Counter are useful, there's really nothing to counter Special Attack moves other than Bide. And there are a LOT of Super Effective moves that are Special Attacks.
