Forum:Power bond

Can power bond be used for Chimeratech overdragon to avoid it's effect of taking damage equal to the original attack since overdragon's attack is ? and not a certain number no damage would be taken right? you would also not gain double the attack power because it is not defined correct? What about powerbond for chimeratech fortress dragon? I'm not sure i can use it for this card because it says "you can only special summon this card from your extra deck by sending the above cards from either side of the field.Coltman66 12:17, March 26, 2010 (UTC)
