Forum:Breakthrough skill chainable?

Is the trap card breakthrough skill chainable in the grave, for example:

My Opponent has Thunder king rai-oh. I summon gold ninja, discard breakthrough skill to special hanzo, hanzo's effect goes off can i chain breakthrough skill to his effect and target thunder king?
