Here the info.:

1. Abomasnow - Can be seen when facing the 7th Gym Leader or evolve a Snover at Level 40 or catch an Abomasnow at the top of Mt. Coronet; the snowy area

2. Machamp - Can't be found, must be obtained by Tade or by Migrating

3. Vileplume - After you obtain the National Pokedex; go to either Route 224, 229, or 230, catch a Gloom, then evolve it into a Vileplume with a Leaf Stone

4. Alakazam - Can be seen when facing the 4th Member of the Elite Four but other than that, it can't be found, but it can be obtained by Trade or by Migrating

6. Gengar - Can be seen when facing the 5th Gym Leader, but it can't be found, it can only obtained by Trade or Migrating

7. Garchomp - Can be obtained by evolving a Gible into Gabite, then Gaite into Garchomp. Gibles can be found in the Secret Entrance of Wayward Cave. Here are the directions:

1)Start at the entrance to the normal cave
2)Take 1 step right
3)Take 8 steps down
4)Take 12 steps left
5)Take 5 steps up
6)Your There

8. A really good Ground Type Pokemon, to me, would be Hippowdon because his High Attack and vase variety of moves

9. A really good Dark Type Pokemon, to me, would be Honchkrow because it's High Attack and Special Attack

10. A really good Steel Type Pokemon, to me, would be Steelix because of it's High Defense and Special Defense

Hope this helps you!!!
