The only thing I had some trouble with was Kiawe and Mallow's trials where it took me 3 tries to beat Kiawe's Totem Pokémon and 2 to be Mallow's and even after starting over with Incineroar (I'm not really like Incineroar too much and prefer Decidueye) I still struggled with Kiawe's Totem Pokémon (Even though I beat it on the first try). Aside from that, there wasn't much of anything in SM that was too hard. I'm not even done with my 2nd go around with Incineroar and my team is already Lv47 to 53. So My Greninja is already as strong as the E4 and I JUST finished got to the Final Island and haven't done the final trial yet.
Although Alola has some better Pokémon than I thought. Charjabug has been one of my primary fighters and Oricorio is something that isn't as bad as I thought, but I'm definitely never going to use again. I haven't had internet the past week so I couldn't look up what moves it can learn. After I'm done with this run with Incineroar I'm going back to Decidueye. I have Greninja so I don't need to try things with Primarina, plus it's a bit too feminine looking for my taste (I've always had a habit of making my team consist of male Pokémon unless the Pokemon in question was feminine looking in design than I'd made an exception) and has some bad physical stats (Which can be made up for with Reflect) and speed but I don't want to go through the arduous task of resetting until Popplio becomes a female when there's 1/10 chance of that happening.
On another note, I'm planning on going around with Decidueye again and aside from Sylveon. Kommo-O, and Greninja I want to have different Pokémon for my team. I also plan on using Vikavolt again so I need one last good member, any suggestions?
Smogon Frog is now my favorite starter Pokemon
