where can i find a bnib blitz striker?

I looked for it everywhere, i just can't find the metal fury version. Can you guys help me?
That's right, even if way lighter Hasbro's one is made in a single piece. So it doesn't suffer about breaking problems, plus i could use it in the ltd format...
I've intentionally skipped Hasbro hollow version Uncertain as being much weaker. But limited format gives it another use which I did not think about because we did not have any metal tournament since 2013.
