Help finding manga (SOLVED)

[Reiru]

So this is actually from reddit post.
Did anyone know, or have a guess?

I am looking to get some help with finding the name of a manga I read maybe like... 15 years ago? I only ever read the first volume of it and I check it out from my public library, but I have had no luck trying to find it. I was able to find it a few months back but I completely forgot the name. Some things I remember from it are.

1. The main character(s) were either in middle school or high school.
2. There was a world tree in a mirror dimension that; the main plot took place in a "mirror" or "reverse" Japan. I am not sure which it was, but I specifically remember Japan being mirrored vertically and it was am alternate reality, but the main cast is from normal Japan, and somehow end up in this mirror world.
3. This world tree was responsible for basically creating or birthing all the monsters that would be used as summons, and they were all represented as cards. They grew on the tree like leaves.
4. The manga pretty much immediately starts with a tournament arc.
5. Male MC; very typical younger plucky MC, reminds me most of ash. I do not know what he fought with unfortunately.

This is what I was able to remember from the manga, it has been a while so I'm not sure if that is all correct, but I put down the information I am at least confident about.

Thank you for any of your help.

Sorry for the very late answer, and thanks for the help.

Unfortunately the original op on the reddit went silent after i give the guess answer from you, and wait the whole 1 week, we won't be able to know if it's correct, or not until he reply.
