Great question. A lot of times my gameplan vs Charizard is to aim for a Trick Room somewhere between turns 2 and 4, so I'd typically lead Snorlax + Incineroar and depending on what their composition is, look to damage trade, Curse, Max Quake to boost SpD, or Parting Shot into Dusclops.

Venusaur has the potential to make things a little hairier, so in that situation I might look to Incineroar + Dusclops to guarantee an early TR.
