Looking for a Spell Selection Guide

[Sysryke]

I found either an article or full guide years ago for choosing/preparing spells.

This guide wasn't about specific spells, but about good general strategy and tactics. It talked about how to choose spells to cover the different types of saves, defenses, and other circumstances a caster might face from day to day.

I think I either found it on these threads, or I was directed to it from this community. There's no way I can crawl through years of posts to find this though. Can anyone point me to a good guide?

Just to clarify, I'm almost certain this was not a class guide. I've been combing through the Guide to the Guides, and I haven't found the article yet. Also, not looking for any specific spell recommendations. Hopefully people catch this in this OP.

Thanks for any help :)

it's not that difficult as it depends on your spell list, Class, feats, and the Campaign. Later past 7th level prepared casters can start leaving a spell slot open here and there.
There are a lot of spells but half are not that great.
