I really hope you don’t mean a Duncan Freehand Magnesium, that’s one crazy expensive yo-yo for someone who doesn’t seem to know how to bind. Anyway I would hope a yo-yo that pricey comes unresponsive, so here is the video you need to get it back to your hand. http://yoyoexpert.com/learn/030-intermediate-bind-returns.html
This feels like a troll but I’m always willing to help if I actually have any knowledge on the subject matter.
I think he means FHZ(I hope at least), Because I’m pretty sure they are Out of Production. What parent would buy there kid a MG(I wish Mine Would). But, learn to bind or lube it.
