Forum:Blackship of Corn Effect in Main Phase 2?

Can I use the Effect of Number 50: Blackship of Corn in my Main Phase 2? It is really helpful at dealing with opponent's Fire and Ice Hands but I'm not sure if that actually works.

I've been told that it works because it does not specify that it has to be your MP1, but I've also heard that the "cannot attack this turn" part of the effect implies that it HAS to be used in your MP1, so I'm not sure. I couldn't find anything on the Wiki either. --BronzeJohnson (talk • contribs) 20:37, August 29, 2014 (UTC)
