Jace Vryn's prodigy price dipping

So four days ago I was drafting on Magic Online and low and behold pulled and sold a Jace, Vryn's Prodigy for 86 tickets. Since then you can only sell a Jace for 67 tickets on Magic Online that is a huge decrease! So what exactly is the problem any ideas? I have a strong bet because fetch lands are rotating Jace is less likely to be splashed. Well that is all for now, we will see and remember to visit!
