Where to Start Using Mnemoics to learn a Language

So I have been slowly learning mnemonics techniques over the last 6 months, mainly with numbers and cards ( I use a Dominic system that I am comfortable with). My end goal is to become efficient at learning new languages. To start I am choosing Spanish as I learned a little in highschool. My goal is to become fluent quickly, having a solid understanding of their sentence structure, phrases, and decent vocab.

My question is, what mnemonics systems, books, etc are available and would be a recommended process for learning? I would hope that I could expand the system to the next language. I do not need to find the perfect system, just the one I can start applying my time to.

Any help is appreciated. Thanks!
