Ive read everything on the website and Im still confused. Can someone take the time to just to give a brief explanation on how to duel for ranking, points, etc. all that good stuff. I want to be involved in everything. I dont understand where to find other members to duel for all of this, and how it counts.

first of all welcome to PDA
you can duel Ranked by Battle Arena
you can find people to chat and duel with from the chat
you can also gain DPs , Exp , Items .. etc by participating in events we have in PDA

I hope that helped , and have fun

Yes, thank you very much!
