Hmm...
Here's a very rough outline of a Moveset:
Victreebel (M) @ Life Orb
Trait: Chlorophyll
EVs: 6 HP / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Weather Ball
- Hidden Power [Ground]
- Leaf Storm
- Synthesis
Weather Ball for obvious Reasons, Leaf Storm for STAB, HP Ground for Fire Types. I'm thinking Fire (or Water if rain comes out), Grass, and Ground types will give me some nice coverage, and a Sun-Boosted Synthesis will help the Life Orb damage. Thoughts?
Also, Venusaur's SpA was 299, *4 with 3 Growths under the sun, makes it 1196. That plus STAB and Life Orb makes it INSANE.
