Notes:
- Starmie is preferred to Calm Mind Suicune because it speeds up wins considerably
- Choice Band is given to Swampert because it gives a lot of Earthquake OHKOS, plus it can't do much else (Surf/Ice Beam don't complement Starmie and Gyarados' moves well, and Cursepert is just bad)
- Electric types: Switch to Swampert and EQ
- Strong Normal types (Snorlax, Ursaring, etc.): Switch to Gyarados or Swampert, depending on the situation
