Forum:Double siroco Q?

If I control two siroccos can I activate both of their effects on one and how much attack would the one have? Also if I do that can I activate Forbidden Chalice during the Battle Phase giving the one sirocco 400 more attack and during the End Phase since Sirocco's effect is negated it won't lose the power boost but still loses 400 from forbidden chalice. 2irishman2 21:20, November 22, 2009 (UTC)
