Sorry, this potentially complicated question is hard to answer in so few characters.

My opponent has Noble Sacrifice in play and I attack with an Ogre that has the 50% chance to attack the wrong target. Will the Noble Sacrifice get in the way of the Ogre's attack?

• This depends on the order each card was played.
• If the Ogre was played first, his ability will trigger first upon attacking, and the Noble Sacrifice will get in the way of the Ogre regardless of what he ends up attacking.
• If Noble Sacrifice was played first, the Noble Sacrifice will trigger as soon as the Ogre attacks and GET DOWN, then the Ogre may trigger his power and can potentially miss the Noble Sacrifice.
