I've been playing Pokemon since Blue was released, and I've gotten pretty good at it.
My strategy? Speed and power above all else. Are defenses important? Sure. Are status moves effective? Definitely! Is it as important, to me, as striking hard and knocking the enemy out flat before they can act? Not really.
Favored type? Flying, as that type fits best in my strategy. Do I mix types? Of course! But if ever I were a Gym Leader, that's the Type I'd use.
Next favorite types: Dragon (they're awesome!), Dark (again, awesome, and pretty tough), Electric (again, speed and power), Fire (there needs to be more of the guys!), Water (the most important Type of all!).
Least favorite Pokemon? Koffing. Thank you, Soulsilver, and thank you, Petrel, for setting my dislike of Koffing into concrete. They're tough, they blow up, and they're smiling. (Darumaka, by the way, is right up there next to Koffing.)
What type of Pokemon I'd like to see in the future? A Water-type Pokemon that looks like a dolphin. Its preevolved forms would be cuteness to the max, and its fully-evolved form would be badass and/or epic. And it just needs to be done!
Favorite Generation? Fourth (D/P/Pt). I love them all, but the Fourth Gen is where I really started getting Pokemon in terms of strategy. It has Giratina, currently my favorite Legendary of all time (next to Lugia), as well as the franchise's first female Champion, Cynthia, who I liked as a character and presented my first real challenge.
Do I Nuzlocke? I do.
Important: I speak from my mind, and if I have something to say I'll say it. I mean no offense; I have no enemies on the Internet, and I plan to keep it that way. And remember, I'm only trying to help.
