I'll start with a simple scenario. In this problem, assume all IVs are 31, all natures are neutral, and all EVs are 0. "Barkers" is an unknown Pokemon. Begin turn 1. Salamence's Intimidate cut Barkers's Attack. Trainer withdrew Salamence and sent out Raikou. Barkers used something. Begin turn 2. Raikou used Calm Mind. Barkers used something. A critical hit. Raikou fainted. Trainer sent out Pikachu. Begin turn 3. Barkers used something. Pikachu used Substitute. Begin turn 4. Barkers used something. Pikachu used Rain Dance. Begin turn 5. Barkers used something. Pikachu's Substitute faded. The question is: What move is Barkers using ("something" is the same move each time)? As an added challenge, Barkers can be one of two Pokemon. From the following scenario, which one is it? Begin turn 23. Player switched in Barkers. Trainer switched in Pikachu. Rain continues to fall. Begin turn 24. Trainer switched in Mewtwo. Barkers used Rest. Rain continues to fall. Begin turn 25. Mewtwo used Hidden Power. It's super effective! Barkers fainted. The rain stopped. Note: I somewhat gave away the answer on Shoddy, so if I was talking to you on Shoddy earlier, don't give away the answer.
