Forum:Book of Moon, Main Phrase 1

Hello, another question to ask. Tried looking in Rulings, didn't seem to solve. Anyways...

Let's say I have a monster face down, and a Book of Moon set. Then my opponent summons a monster, then uses Mystical Space Typhoon on my BoM. I chained it and used it on my opponent's monster, and it still Main Phrase 1. Does he/she still able to flip it face up? I know during Battle Phrase, you can't, but MP1?

And, let's say if it was the same situation, but the opponent already has a monster on the field. Can they flip it face up? THank you! Zlilyeakidz (talk • contribs) 03:45, March 1, 2011 (UTC)
