I am going to use heatran it have to be a Calm nature Toxic Staller variant because I know P2 are defensive and another scarfer that deal with gar, zard x, and volc is greninja am I right?One thing you could do is use venu p2 heatran over venu chansey skarm. It’s a lot safer in some aspects and more adaptable and less momentum draining when not brought as a core. P2 also is less likely to get trapped by gengar due to trace. That’s only a brief suggestion as well as perhaps running another scarfer over chomp that can deal with gar since you already have mamo. You want a rock move on that scarfer for sure vs zard x And volc anyways.
