>>16828167Up against the steel and fighting gyms, he won't be stellar. However, once you clear those, he'll be amazing against every other gym, especially the dragon gym. He will also rip through Team Rocket like a monster truck through tissue paper. He is a physical beast with enough speed to beat most things you'll come across and a decent move pool.
Definitely a good chooice, though you might consider picking up a bulky water type soon. Quagsire comes to mind.
