Just some updating
move 4: Toxic / Roar / Ice Beam
From the Wish Support set, can you move Roar to first slash, and Toxic to second slash please. Both have merit, but being able to phaze out pokemon like perhapes Lum DD Dragonite and shit is useful. Vaporeon is also often used on balanced / defesive teams which often have heavy hazard support which Roar can also abuse.
-Secondly can you update the Checks / Counters section a little bit. Virizion and Shaymin (and Breloom with Poison Heal) are relatively rare so im not sure if they need to have a big mention. Maybe add Venusaur which usually does a great job forcing out Vaporeon (especially as its commonly used on sun teams which cuts Scald's power) and is a good deal more common than Shaymin.
-Don't merge the Hydration Wall / Wish Support sets. It gets far too slashy, and the sets do play slightly differently (since one set trades the ability to pass wishes to teammates, while the other has a better healing move and no weakness to Toxic which is a pretty big deal.
