Forum:Koa'kis vs Return from the Different Dimension

I was wondering which effect activates first?

Koa'kis destroy themselves during the end phase if you don't send Iron Core or reveal the required card.

And Return brings them back from the rfg pile and removes them from play during the end phase..

So which one activates first?
