Ok this is like the only way I will be able to get a national dex so I..

You can beat the E4, you know, to find three of them...
And for the other two, why don't you battle trainers?? Why doesn't anyone on this site battle anyone? It's good training, you know. Why avoid the trainers?

#46. Wormadam- from a beauty on Route 214.
#65. Drifloon- in front of the Valley Windworks every Friday. Or, you could have found a few from trainers in the Hearthome Gym.

#108. Spiritomb- from the Champion of the E4. Nowhere else.
#111. Garchomp- refer to Spiritomb.
#139. Milotic- refer to Spiritomb and Garchomp.

45 is wormadom which is seen by a beauty on 214. 065 is drifloon which can be caught on fridays at the windworks. The rest are owned by the Pokemon league champion.

# 139 - Milotic see at Pokemon league Champion

# 111 - Garchomp see at Pokemon league Champion

# 108 - Spiritomb see at Pokemon league Champion

# 065 - Drifloon find besided grass at valley windworks only on fridays

# 046 - Wormadam I forget where to find him

#046 is WORMADAM evolved from BURMY
#065 is DRIFLOON you get him at the wind works on fridays
#108 is SPIRITTOMB you see him after you beat the E4 the champ has him as his first pokemon
#111 is GARCHOMP you see him in the same place as #108 only it comes out at random
#139 is MILOTIC again same as #108 and 111 it is the 5th Pokemon the champ has

Thats it and your well come

139=Milotic must evolel Feebas with high beauty

111=garchomp evolel gabite Lv 48

108=spiritomb talk to 32 people underground then go to hallowed tower. Have odd
Keystone.

065=drifloon go to vallywindworks on friday

046=wormadam evolel burmy at Lv 20

#46 Wormadam- you can't see this in the wild but trainers around the Eterna forest should have one. If they don't, you can evlove a Burmy into one.
#65 Drifloon- trainers at the 5th gym in Hearthome had this. You can see one by the Valley Windworks on a certain day of the week by slathering honey on the tree. I don't know which day and Im sorry I can't be more help with this one. #108 Spiritomb- the Champion has one. You can also get one by the hollowed tower south of Solaceon town but you have to talk to 100 different people in the Underground to see one there. #111 Garchomp- some of the dragon tamers in Victory road have one. You could also get a Gible in the Wayward cave under the bike path and raise it to 48 when it evolves. The Champion also has one of these.
#139 Milotic- You can't see one wild. You could catch a feebas in the part of mount coronet that leads to Snowpoint and get it to high beauty to evolve it. Once again, the Champion has one. I suggest you work on beating the elete four because all of these last three are very hard to find.
