So, say you are in this situation. You have your Pokémon learn Wonder Room, and it is a frail Pokémon. You get a nature decreasing your defensive stats, and EVs devoted to offensive stats and speed. You go up into someone in competitive, and lead with this Pokémon. You use Wonder Room, and now they’re Pokémon is very weak, and yours having the advantage. Would doing this be a viable strat? The only knock backs to it is if the user has HP not Defense like Chansey, or they are frail, like Lucario, so you don’t gain all that much from using Wonder Room. Is this viable?
