Easy victories int the beginning
Walk around Viridian Forest for a while.You can find a pidgeoto (sorry for my bad spelling) Lv. 8-9! [Make sure you have an alternitive Pokemon if Pikachu is too strong for it! And bring lots of Poke balls!]If you catch it you have a pretty strong Pokemon that can beat most of the wild pokemon! Also after you get Pidgeotto, [or before] catch a caterpie, and train it into a metopod, then a butterfree. This makes it easy to beat brock. Or to beat him catch a Mankey to the West of Viridian city and train it until it knows Low Kick.
Hopefully I helped some of you out there!
Thanks for reading!
