I've started a new game on platinum,and things are going good.My starter was turtwig,cause I've played and finished the elite four with the other two starters.
At the time of first gym,I had:
Turtwig lv 11
Luxio lv 15
Machop lv 13
Machop just smashed roark into the dumps. XD
Anyways,by the time a reached the secong gym:
Luxio lv 19
Machop Lv 22
Grotle lv 19
Buizel lv 17
I lost twice here,cause I was weak to her poison type roserade.Then i formed a new plan.I sent Grotle first,kept using curse,got its attack and defence up,then used a super potion on it,and that it,they were gone.
Then by tird gym:
Floatzel Lv 26
Grotle lv 24
Luxio lv 20
Machop lv 24
Ralts lv 18
I was losing because of mismagius' shadow ball.I had to evolve buizel to win.
And then when I finally did reach Maylene:
Floatzel Lv 27
Kirlia-Lv 20
Luxio Lv 27
Torterra Lv 32
Houndoom Lv 25
Machoke lv 28
Very easy,I just tries to get some training for my weaker pokemon,and when they fainted,just used the strong ones.Machoke took care of the first two,torterra took care of lucario.
Now i'm at the fifth gym
Team:
