Forum:Powersink Stone can help Koa'ki Meirus?

I have been thinking: what if I have Powersink Stone active on the field with two counters on it and a card like Koa'ki Meiru Valafar, which has the effect that tells you to discard an Iron Core of Koa'ki Meiru during the End Phase? Since the Powersink Stone has two counters on it, it negates the effects of all monsters on the field, including Valafar's. However, Powersink Stone's counters are removed during the End Phase, and Valafar's effect of discarding an Iron Core of Koa'ki Meiru activates in the same Phase. What I want to know is, is it possible to avoid your Koa'ki Meirus' effect of discarding an Iron Core of Koa'ki Meiru with Powersink Stone? Help would be much appreciated.
