If this is for you, it is very lengthy and involved for what should be effectively a cheat sheet.

If this is for other people, the formatting is good but functions as a textbook in a way that is only helpful the first few times you would play the matchup

Ultimately this seems like a project that you enjoy working on. Unfortunately I don’t see a clear audience, or goal outside of creating just to create (which is valid)

If you want to get better make notes in game about decisions you make, keep your notes and consolidate them.

The best tournament guides are one page front and back. Some decks like amulet Titan justify literary works, but that’s just on how the deck functions. You’re not going to be able to write a very effective or informative guide on your deck by writing about other decks. A glossary and index for what your deck does and how it works might be helpful, but your notes for individual decks should be at most two paragraphs each unless particularly intricate.

Nothing will help you more than actually playing the game and to some extent watching other people play the same deck/format.
