Checker

Checker has noticeably peaked in trading, with it currently no longer being sought after by traders. While its still a noticeably good performing item, it simply isn't performing anywhere near compared to other high demanded items (like Proto-8 or Power1), and is quite a lot more similar to above average demanded items (like Red/Purple LVL5), therefore a demand decrease is necessary.

With clean Checker also peaking in value, dupe Checker has lost majority of the demand that it previously had. It's performing quite mediocre in trading, and does not perform anywhere near compared to other above average demanded items (like duped Power1 or Blue Fire), therefore a demand decrease is necessary.
