Forum:Costs of negated monster effects

If I have Card Trooper in the grave and i summon Debris Dragon can i still use card trooper's effect to mill?

Also If I have Junk Synchron and I summon with its effect Mystic Piper can I still tribute it and it effect goes off in the grave yard un-negated? from Yigiter007 (talk • contribs) 00:56, May 11, 2011 (UTC)
