Countering Omastar

If your eggys have bullet seed I think you will be fine. I would move the victreebel to the back, eggys have higher dps.

Victreebell is useful in that in can carry Leaf Blade, which is better for it than Solarbeam when used near the back of the team, and is also superior to Seed Bomb.

This team is fine as is. Seed bomb won't help you, as it is a low DPS move. Leaf blade on Victreebel is a better move, but you should be fine with the all-solar beam lineup.

Impressive lineup! I don't have quite as many double grass attackers so I have to rely on fighters during cloudy weather (it's very often cloudy here so that's not a big deal).

I countered Omastar with two Counter/DP (yay, what a pun!) Machamps and a Hariyama, right after my lv30 Venusaur. My only highish level Eggy has Extrasensory and I'll probably use a fast TM on him when I get one.
