Le Wonder Room Ab00se:
Hazards Lead: DeoD
Wonder Room Setters: DeoD, Slowbro
The main core of mons that'll take defensive advantage of WR consist of Gallade, Slowbro, and Hoopa. Originally I had HoopaU here in place of the regular as it handles the role much better, but Hoopa still has the bulk to take advantage of a Wonder Room + Assault Vest combo. Mega Gallade has a bulky set with investment dumped into SpDef along with making use of Bulk Up + WoW. Slowbro is just a standard Defense dump who will help to keep the room up when needed.
Strictly offensive members of the team are going to be your Mew and Gardevoir. Expert Belt and Scarf respectively. Scarfvoir is necessary for the dark matchup, and the team lacks any actual speed outside of 100 base Mew. My Mew chosen Mew set is just meant to fuck with players and take names. The standard, bulkier Mew sets could easily be used here instead for an extra Room setter and to further the overall bulk of the team, but gotta go fast.
