Forum:Valhalla vs. DNA Surgery

Hi again guys, sorry for the constant questions. Right now my friend and I are in a debate, if a person plays DNA Surgery and calls fiend and then their opponent plays Valhalla hall of the fallen on their turn, would they be able to use Vahalla's effect? Because when the monster is in their hand it's a fairy but as soon as they play it it become plant. 24.205.31.205 (talk) 00:08, January 17, 2011 (UTC)
