Forum:Confusion with Geartown

Ok, the Rulings here tell me one thing, and my friends and other pages tell me another thing. I understand that the second effect of Geartown is activated when Geartown is replaced by another Field Spell, when it is destroyed, and when it is discarded from the hand or deck, if I am not mistaken. However, the Rulings here tell me that if the card is chained to Magic Jammer, the second effect still goes. So here's the question:

Does this apply to all cards that negate and destroy magic cards upon activation? Or there are some that can fully negate the effect? I am concerned with this, mainly because I see the cards rulings and it just confuses me out of my mind. Thank you in advance for the enlightenment. D-Rogue 16:57, 6 January 2009 (UTC)
