Implement of Improvement

• WWizards of the Coast2017-02-09
  Official Ruling
  If you activate an Implement’s first ability, you’ll draw a card from its second ability before the first ability resolves. If the first ability has a target, you need a legal target to activate that ability, and you choose that target before seeing what card you’ll draw.

  Official Ruling
  An Implement’s last ability triggers no matter why it’s put into a graveyard from the battlefield. You don’t have to activate its first ability.
