Each of your opponent's monsters that conducted an attack while this card was face-up on the field has its ATK halved as long as this card remains on the field. During each of your Standby Phases, pay 2000 LP or destroy this card.
[R u mad noob? :v]
You're the one that is noob, I bet you don't understand ruling
[how fucking stupid are you anonymous second replier fuckerooney? he asked if he's mad kuz OP bitching about mirror wall.]
OP not bitching about mirror wall, but about those noobs like you that doesn't understand the game ruling. You're the one that's fucking stupid.
So? I know it's easy to know when an opponent has it, in fact, most of the time they set this turn 1 (IDK how), the problem is that if you don't have a counter when needed it could cost you the game, not only that, but if they run 2-3 copies it just gets annoying and boring dealing with their cheap tactics, they should limit this to 1 per deck.
Ok if anyone is still interested in this post: I tried my luck to get it and burn Neo-Impact down -> with STILL 29 packs left I got my 1st mirror wall (and in glossy) - very happy about this, could have been way worse :)
I know that sucks as hell - had the same in Wonders of Sky 5 SR in the last 12 packs :/
but at least we know what to get at the end; I think thats kind of fair (otherwise in pure random generator there you could buy 500 packs without mirror wall or so^^)
