For Hidden Blade, does the player still draw a card if the target unit doesn't die or leaves the battlefield?

Ruling: The player draws a card even if the target unit doesn't die, because the draw is not conditional on the death. However, if the unit is removed from play (by effects like Gust or Retreat) before Hidden Blade resolves, there is no draw because the game cannot determine "its owner".

Nuances:

• The draw happens regardless of whether the unit dies from the damage
• If the unit is no longer a legal target at the battlefield when Hidden Blade resolves (removed by Gust, Retreat, or similar effects), no draw occurs
