Is there a guide for planning future battles?

[DecShep]

I 100% blame myself for this, but an issue I have noticed I have is I don't plan ahead properly. I didn't get a Rain Dance TM before Agate and I should've put in that effort to catch beldum for Samson and many other things. 

 

I see many gyms that are hard, are easy to beat with specific Pokemon (like Hawlucha for Samson/Lycanroc+Bronzong for Charlotte etc) but I don't stop to think and catch certain Pokemon especially since I don't know whats coming. 

 

So is there a guide that shows useful tips like to catch certain Pokemon at specific times or get certain items? It was very time consuming (again my fault though) to go all the way back and find a rare Rockruff then EV train tf out of it and go back and do the same with Bronzong etc. I just want to know ahead of time while I'm already somewhere, plus I'd love to stop annoying everybody here with posts because I suck ass lol

 

Anyway, thanks for the help!

As far as I know currently there is not a detailed guide telling players everything there is to find, catch or do before each Gym Leader all in one: there are item and pokemon location guides, though, as well as sidequests guide iirc. If you're so worried with making "how to beat X" topics, why not use the search function if you aren't already? You're not the first (and not the last) to struggle against many of the Gym Leaders - there's even a thread dedicated to helping people to defeat any Gym Leader. You can always ask there if you don't feel like creating a new thread each time you get stuck.

 

In many cases you can go back and take the time to train new mons and explore areas more thoroughly. One thing you can do to prepare for future battles is to train and use mons in rotation (more than 6 so you can pick and choose your team for each Gym / PULSE etc.). Going through the trouble of catching and raising more mons can save you headache later on. Besides, having specific counters to Gym Leaders are nice to have but not mandatory by any means. There is value in figuring out your own winning strategy - I imagine quite a few people did, and this is why you get different advice from folks based on their experiences. Your playthrough is unique to you, you're not being hand-held by a guide revealing you the optimal/best strats.
