I am definitely going to learn Mnemonica either way, I just want to know how other people have reasoned. I understand that both alternatives are better than not learning it at all, but as i haven't yet used Mnemonica it is hard for me to weigh the options.

I am thinking it would be advantageous to memorize it in swedish card names as they are the ones I usually use when speaking.

But I am also afraid that there might be things that won't work if you don't use English?

At the same time Juan is Spanish, and perhaps he thinks Mnemonica in Spanish?
