Mewtwo (PC/FB) taken down with 4

- Partly cloudy weather (rock + normal boosts)
- 4 players (33, 40, 36, 33)
- Not the most optimal counters
- I was simultaneously helping an old man nearby type an address into his phone for roughly a minute (in other words I wasn't dodging)
- ~10s remaining on the clock
- Fortunately this one had PC and not confusion (and something other than shadow ball was also appreciated)

Reflecting on it, there was probably a lot of room for error in this particular raid; had we all had optimal counters + say foggy (unlikely) or rainy (for bug) weather it could have been easier

Has anyone had a similar experience with 4 players? Could a PC + either HB or Psychic be taken down with 3 a in different weather?
