Forum:Iron Core of Koa'ki Meiru Question.

So I have a question about the Iron Core of Koa'ki Meiru. If you have more than one in your graveyard and skip your draw phase, are you allowed to pick up all of them? The cards say that you can pick it up instead of drawing, so wouldn't it let you use that effect for all of them if you choose not to draw on the turn? Also for the second effect does it activate during the draw phase, or can you discard any time?
