I would almost always choose mixed Venusaur unless I really wanted to use Weather Ball. Earthquake is good, and so is Venusaur's superior bulk.
It is a shame you tilted. Mind if you show me your Meloetta team? I also hate doing tilts like that too, although I rarely do those anymore. :(
By the way, I will talk about the peak you did later. Don't worry, I am pleased.
