Miltank was a huge pain in the bleep...... I managed to defeat her with my starter, which only had 1 HP left....
well lots of people complaints about that too.
I remember that I thought I could sweep her with my Quilava but when she started using Rollout, I went "bleepUUUUUUUUUUUUUU-". And that's when I decided to use a combination of my Gastly, Sandshrew and Quilava to beat her.
Gastly was because of his Ghost type. Sandshrew was because of his Dig attack. Quilava is to finish the kill/revenge.
Morty's next... Hopefully he's not too hard....
Easy, just don't use Fighting types. Ghost hates Dark and other Ghost types. Because Gastly, Haunter and Gengar are Ghost/Poison, take advantage over their Poison type and use Psychic and Ground to hit them hard. If you don't have any of those, you can use a Normal type's Foresight and/or other elemental attacks.
However, watch out for Mean Look. Gengar's bound to use it. Also, the rest would use Curse. If that happens, switch out immediately until the opponent's current Pokemon is defeated. I had my Togepi act as defense and luck on Metronome.
I beat Morty! It was actually kinda easy, since I easily killed all of the Medium's Pokemon in one or two hits by using fire-type moves, and the same pretty much applied to Morty.
I would've won only with Quilava, but he fainted so I used Togetic as back-up.
so i use bite.
Bite is a good Dark-type move that can be learned by a versatile field of Pokemon.
Sucker Punch is a good move too, but it relies on the opponent using an attacking move, which kinda sucks.
