Man, what's this? The whole point of Reborn is to gbring a deep and well-elaborated story plus challenges throughout the gameplay. Gamefreak/Nintendo produces easy pokemon games since ever. They are nice to play and all, but you can easily just beat everything using only your starter. Reborn demands you to think your team and movesets, even if you are not 'doing perfect met play'. Reborn gives so many options to build your team, that I didn't mind farming pokemon up. Also we have online play and a lot of players willing to trade well trained mons, just ask :P. I've beaten reborn (so far) with two well trained teams of 6 mons, didn't need to use anything else. I did put a lot of effort to get them, yes, but it was worth for me. I hope you enjoy Reborn more ^^
@MuchoG I favor more tend to favor more fast mons so I would advise you to take out Walrein and Ampharos. They don't fit my play style, that's all. Aggron would stay if you want some tank/setter with Stealth Rock, I'd take him out too. Alakazam is hard to use in Reborn so far becaus we don't have access to its best moves yet (Shadow Ball and Energy Ball) so you would end up having only Psychic moves, and in a long fight like that, variety is a need.
I'd give movesets for every one but damn I'm lazy today. So I'll just tell the team I'd use based on your mons: Blaziken, Lycanroc, Galvantula, Sharpedo, Roserade, Jynx. This team doesn't repeat types so you'll have 12 STAB options. The problem is: to have the variety I said, you'd need to have them bred to have all the good moves. Other good options would be: Skuntank, Misdreavus, Honchkrow, Croagunk and Houndour.
If you want, I have all of them well-bred and ready to trade. See ya~
