How do you know when an item was removed?

[Tobius]

How can you tell when an item was removed on live and/or here.

I'm trynna find out about Tagashins bone mask but can find very little on allakazam.

He was removed sometime between 2001 and 2008 apparently [You must be logged in to view images. Log in or Register.]
His mask doesnt seem to have an allah page or 99 wiki page.

Wanna know if it's worth camping him.
