Forum:Blackrose v. Crystal beasts

I have a question about crystal beast's effects when I use cards like black rose.

Player A has 4 crystal beasts in his/her spell/trap zone. They also have 3 crystal beast monsters on the field and a Rainbow City field card.

Player B is able to synchro summon a Black rose Dragon and activates the nuking effect.

Can player A use the crystal beasts' effect to send 1 monster to the spell/trap Zone and STILL protect his field card via effect? Shikaru777 01:58, February 25, 2010 (UTC)
