If an opponent plays Falling Comet (which targets units on the battlefield) and you use Flash to move your unit away from the battlefield, does the unit still die since it was already targeted?

Ruling: The unit does not die. When a spell resolves, the legality of targets is checked again, and since the unit is no longer a legal target (not on the battlefield), it is not affected by the spell.

Sequence:

• Opponent plays Falling Comet targeting your unit on the battlefield
• You use Flash to move your unit away from the battlefield
• On resolution, target legality is rechecked
• The unit is no longer a legal target and is not affected
