I'm not super competitive about it but I at least put in some effort into winning so I can get more prizes. They've improved the matching system now too so that you're not more likely to face someone within your own rankings, not like pitting a Gold player against top tier KOG players
i didn't notice the matching system much but my best deck that is meta i can use is a blue eyes, neos, and 6 sam. i got partial to mostly darklord deck. i can't get motivated in pvp.
the one thing i wonder i been part of some teams where i'm the only one in green ranking yet i run into ones that green ranking even if the rest are yellow and red?
