Why is this combo almost unstoppable?

So I was just tinkering around with my plastic bey's, and I don't remember wheere I got this from, but the customization is almost unstoppable. Every beyblade I battled it with lost. . anyways, here's the customization:

AR: Bistool
Weight Disk: (forgot name, but it's the smallest heaviest one)
Base: Master Draciel

I'm not using a magna core or the weighted core, just a normal one. But, my question is, what makes this customization so unbeatable?
