if weezing is a huge problem for you (i personally never see it), you could try Substitute / Endeavor / Belly Drum / Play Rough on Slurpuff as it still allows Slurpuff to weaken Ferroseed (although not as well as Flamethrower) while also being able to lure Weezing in as it will try to wall you just to Endeavor it and get it to low health, which should open the way for the rest of your team.
