Take care of yourself.
Unfortunately, this replay doesn't qualify for the achievement, because:
The opponent forfeited with 3 Pokémon left, making the achievement invalid.
- You may count battles that end in forfeits if the opponent has 2/1 Pokémon left (assuming they started with at least 5 Pokémon). You may not count battles that end in forfeits for achievements that say "no forfeits".
