Blue Dragon IS type specific, and most of the Summoners and Empowereds are actually kinda weird as they feel disjointed. Only a few are Normal monsters support, others are either type specific or generic, or deals with Pendulum Summon.
The whole thing is awkward to use, really, which is why the archetype never made any influence, not even a small one.
Hmmm, Blue Dragon. White Tiger. Hmmmmmmmmmm!!!! LMAO.
Im using this guy in a yami yugi deck with spellscasters and warriors. It has a total of 1300/2000 stats and a great effect, very good to instant summon a high atk normal monster, or set up a lvl. 5-6 summon next turn if i summoned in def pos. by the marmiting captain.
