Because Umbreon was my powerhouse of the team of two, I relied on only using Umbreon, when the gym leader was on his last pokemon (I guess an Onix...?) (Current team By the way
Umbreon- Lv. 20(It has to be that level to have Faint attack)
Pidgey- Lv. 12 (I trained it without saying XD) )and Umbreon was at Half HP. I taught Umbreon a secret move that I told it to hold back on using, the Gymleader told his Onix(Not sure if it is) to use Rock Tomb, and I told Umbreon to use Dig to dodge and Umbreon went Underground and tunneled under Onix(?) and used Faint attack, Onix took considerable amount of damage and Umbreon stayed underground, the Onix used Rock Tomb into the hole Umbreon made to try to get it out of the ground, and Umbreon used the second Half of Dig (The actual damaging part) behind onix, getting it down to 1 HP, I decided to switch for Pidgey, Just because it needed to do ONE damaging attack, Pidgey flew up to Onix and perched onto its head and pecked it like it would on the ground, unfortunately, this didn't damage Onix cause it cannot learn Peck, so it used Gust insetad and KOed the Onix, but was also KOed when the Onix fainted because it fell under the Onix. I returned Pidgey into its Pokeball

(Yeah, it's Onix. LOL Onix fell on pidgey.)

(Pidgey's gonna be the possible troll of my Pokemon Team.)

Oxy headed to the gym to take on Brock.
Yalko trained up his pokemon.

After getting the Gymbadge I left the Gym to train some more

Hailey and her Sandslash started going towards Naidiriv City.

Being right outside Retwep City, I was still training Pidgey and Umbreon

The two walked up to the Naidiriv City Gym.
"Huh. No one home?" she asked, reading the sign on the door.

I caught a Caterpie and continued training

"I guess we're going to Retewp City then." I told my Sandslash.
"Slash." it replied.

I leveled up my Pokemon until Umbreon was Lv. 28, Pidgey evolved and was Lv. 20, and Caterpie evolved and was Lv.19

I found a random wild Mankey, so I captured it. It was level 3.

I go to Retwep City to pick up something at the museum. I decided to put that off and talk to Kcorb.

I trained the Mankey I caught.
"I hear the Gym Leader of Retwep City is a rock-type trainer. I wish we could find a good water-type." Hailey told her Sandslash.

I overheard a trainer "You have a Ground type, You're already set" I said to the trainer walking over to her
