Venosaur's most powerful move is Solar Beam, all starter Grass-types will learn Solar Beam around level 60. Solar Beam's main weakness is that it only has 5 PP, but it's sheer power makes up for it's low usage with 160 power.
I Have this move set Flame Thrower/ Flare Blitz (Your Choice ) Blast Burn Hammer Arm Scald
Rest, Sleep Talk, Earthquake, and Zen Headbutt.
Trasmorm False Swipe Metronome Hyper Beam
earthquake,take down,hydro pump,and dynamicpunch are in my opinion.
When you set a move and press L+A you use the move.
