Well I headed south to Pastoria City and along the way I captured a Houndour, female, level 28. I trained it vs. the Psychics and the Vs. Seeker until it learned Fire Fang at level 30, then I evolved it. After arriving at Pastoria City, I went to the move tutor house and re-learned some moves, such as Swords Dance for Empoleon, Cross Poison for Crobat, and Grasswhistle for Roselia. I'm also going to teach Houndoom Thunder Fang.
Then I went to the gym, easily beat my rival, then went inside. Handled the trainers there with Roselia, then the gym battle... it really pissed me off but I won. 2 of his Pokemon didn't even give me Exp. because mine fainted as well.
Vs. Gyrados... he killed my Roselia and Gyrados fainted due to poison. No EXP gained.
Vs. Quagsire... I beat it with Crobat I believe. Empoleon fainted due to Mud Shot and loss of speed.
Vs. Floatzel... I sent out Rampardos after Crobat fainted since Floatzel was already in the orange health, because it was all I had except Houndoom, and Houndoom would've easily lost. Floatzel used Aqua Jet and brought Rampardos down to low health, but I had chosen Take down before that, so Rampardos and Floatzel both fainted. No EXP gained there either.
