Help With My Team

[tygaa2]

You can definitely build a good team around Gyarados and Breeloom. There is a great post about ev training on this site here EV train . For breeding you need to start off by getting a 6iv ditto. This means that in all 6 stats (HP,Atk,Def,SpA,SpD,Speed)  it has the strongest IV stat possible. If you need one I can trade one to you. There are also natures that every pokemon have, these increase and decrease stats depending on what nature. I have included a picture below. While breeding if you make a pokemon hold an everstone its baby will have the same nature as the parent. If you have any more questions feel free to ask.
