Forum:Field Spell Card Questions?

Okay, Changing the field means destroying it, right? My question, Ex. I have an active "Ancient City - Rainbow Ruins" and I'm controlling 1 Crystal Beast card treated as continuous spell card on my spell/trap card zone, so the 1st effect of my field is now activated that when I have 1+ crystal beast on my spell/trap card zone, "Ancient City - Rainbow Ruins" cannot be destroyed, now my opponent activate his own field spell card to replace mine. Do u think my Field will be destroyed even though I'm controlling 1 crystal beast monster on my spell/trap card zone or the field he activate will be destroyed?

Another, Mystic Plasma Zone with a counter(card guard counter) to protect the field, same as above, do u think it will be destroyed if he/she replaces mine? ThanksAllan0015 (talk • contribs) 04:39, April 20, 2012 (UTC)
