Forum:Chain Whirlwind targeting self?

If my opponent has two face-down Spell/Traps and I use MST to destroy one, can I use my set Chain Whirlwind to destroy the other and itself? Because it needs two cards so I think... Can it target itself? I remember that MST was able to target itself but I think that was changed... Help please! -- LordGeovanni - ( Talk To Me ) *Kupo* 18:17, November 14, 2010 (UTC)
