Elric, I may not be very experienced on monotyping myself, but I think you should first play water, fire or flying. They are easy to find/get, especially fire/water as you start with one. Flying are also pretty easy to get, and can reward well. Anyways, no updates for now but going to continue my game now.
@Update: Another brief update.
-Defeated Lt. Surge after getting CUT on Ship.
-Defeated rival on Ship as well as all other trainers there were.

-Lance's dragonairs proved useless and dragonite only made me use one full restore. His aerodactyl killed Charizard once though.
-Bruno wasn't tough but made me use some full restores.
-Beat my rival, the champion. His Blastoise was tough. I luckily only used one Max Revive because I did a critical hit with EARTHQUAKE. So yeah, lucky of not needing to use my other revive.
This was almost a solo run, since my team is:
All of these were around level 20, except for the LV 74 Charizard. The Gyarados was a HM slave with Strength, Surf and Rock Smash.
