I was answering This Question and since the new player Pokémon doesn't affect the power of Future Sight, what if the new player Pokemon was Tapu Lele or Indeedee? Would the Psychic Terrain generated by Psychic Surge give Future Sight the 30% (Or 50% If you're in Gen 7) boost?
I've already looked at the Bulbapedia entry, and it just says that "Affected Pokémon get the power of their Psychic-Type moves boosted by 50%" (30% in the Gen 8 update.) Since the original user of Future Sight is not affected by the Psychic Terrain, since they're benched.
I would like some evidence, like a replay or somewhere where it directly addresses this scenario.
Thank you.
