"What Dragon type Pokemon has the best move pool/coverage?"

Currently putting together an all Dragon team and I've come to the conclusion that im gonna need one team member for type coverage. So that being said, which dragon types have the best move variety in their learnset?I'm also open to using any Pokemon that are technically not dragon type, as long as they can at least pass for a dragon. For example, Charizard and Gyarados are most likely going to be a part of the team even though they aren't dragon type, but I mean, someone tell me how they aren't dragons.Edit: Just for clarification: this is mainly for a Pixelmon server me and some friends made recently. So no restrictions, every Pokemon is available with their most recent move pool being the one that's used in game. via /r/pokemon https://ift.tt/2TdpmQx
