Forum:Chaining targeted cards

Can I chain a card that has been targeted by an effect that will destroy it? Here are two examples. 1) Trap Master is destroyed and my opponent select my face down D.D. Dynamite. Can I activate it? 2) My opponent plays Dust Tornado on one of my face down cards. Can I activate in chain that card before it is destroyed (let's say it's a MST)? Thanks. 78.14.41.13 (talk) 16:54, April 23, 2011 (UTC)
