Mine knows Solarbeam, Earthquake, Growth, and Petal Dance but I'm really starting to dislike Petal Dance as it locks Venusaur into using the move while the opponent could just switch his/her Pokemon out. Plus, it would be a waste for Venusaur to hold a Persim Berry while it should really be holding a Life Orb.
I was thinking of switching Petal Dance with Synthesis, Toxic, Leech Seed, or Hidden Power (fire), but I don't know which to choose. Help me out!!
