2. Espeon - As a psychic-type Pokemon, Espeon can deal significant damage to opponents with its special attack and high speed stats.

3. Crobat - This poison/flying-type Pokemon is fast and has an excellent movepool, making it a strong addition to your team.

4. Gyarados - As a water/flying-type, Gyarados has high attack stats and can dish out significant damage while also having a decent HP pool.
