Forum:Can Alien Effects Stack?

say that Alien Overlord and Alien Telepath are both on the field would the opponents monsters just lose 300 ATK and DEF for each a-counter or do they lose 600 for each since two different monsters with the effect are out on the field also Cosmic Fortress Gol'gar isnt considered an alien right? so when attacking the opponents monsters they dont lose anything right?68.180.99.38 09:35, January 24, 2010 (UTC)
