?You will die now, I cannot remove your unit. Unfortunate considering its abilities? he says.

I was reading one of the W'Kar Saga stories, when i spotted this. This is obviously way before Malice' demise, but my question is what changed between this story and the time Malice lost his unit to Anubis.

How did Anubis figure out how to remove W'Kar units?

Well you have to remember that normal unit removes will remove a wkar unit you just need a lot of them

Also that the orginal host of the true wkar unit was a creater and anubis has access to his knowledge

So with these two facts it not hard to belvie anubis could come up with a way to quickly remove wkar units
