Forum:Garoth, Lightsworn Warrior Question

I should probably know the answer to this question since I've been playing with Lightsworns for a while, but I just want to make sure.
 * Situation: I have Wulf, Lightsworn Beast and Garoth, Lightsworn Warrior face-up on my side of the field, and I tribute Wulf for Celestia, Lightsworn Angel. I activate Celestia's effect, destroying two cards on my opponent's side of the field.  Opponent has no response for Celestia's effect.
 * Question: Does Garoth's effect chain to Celestia's effect? I don't think he does because the 4 cards sent to the Graveyard for Celestia are considered part of the cost and not the effect.    Am I right, or have I been playing wrong the entire time?  Thanks!  -- Sub 00:12, 2 October 2008 (UTC)
