I've been using the standard Swords Dance Toxicroak set, which usually runs Swords Dance, Drain Punch, Gunk Shot, and Sucker Punch. I tried switching Sucker Punch for Earthquake, as Earthquake would allow Toxicroak to be able to beat opposing poison types such as Dragalge, Salazzle, etc. However, Sucker Punch can serve as a revenge killing move to weak opponents such as a weakened Shell Smash Blastoise (Even though Toxicroak can check Blastoise) and faster Pokemon. However, I can't decide between Sucker Punch or Earthquake. Which one should I use, and why? If it matters, the other members on my team are Blastoise, Alolan Sandslash, Talonflame, Heliolisk, and Weezing. Pokepaste for movesets can be found here.
