Since you can't go back for several badges, I wanted to make sure I have my team lined up before going. My current roster is:
Mismagius
Shadow Ball
Mystical Fire
Power Gem
Nasty Plot
Tsareena(Queenly Majesty)
Hi Jump Kick
Power Whip
Play Rough
Synthesis
Flygon
Earthquake
Rock Slide
Dragon Claw
Dragon Dance
Silvally
Multiattack
X Scissor
Iron Head
Metal Hound
(I want Silvally on my team, but I'm not 100% sure of the best direction to take him. What's a good MS for a Silvally?)
I like to change up my team every few gyms, and I've already used Incineroar, Toxicroak, Grumpig, Masquerian, Scolipede, Walrein, Palossand, and Roserade, so I won't include those. But other than that, I'm totally open to suggestions!
