: Target noncreature artifact becomes an artifact creature with power and toughness each equal to its converted mana cost until end of turn.
: Target artifact creature gains deathtouch and lifelink until end of turn.

Rulings:

• 10/17/2013 A noncreature permanent that turns into a creature can attack, and its <img src="/Handlers/Image.ashx?size=small&amp;name=tap&amp;type=symbol" alt="Tap" align="absbottom" /> abilities can be activated, only if its controller has continuously controlled that permanent since the beginning of their most recent turn. It doesn’t matter how long the permanent has been a creature.
• 10/17/2013 If the noncreature artifact had any other supertypes, types, or subtypes, it will keep those. In most cases, the artifact creature won’t have any creature types.
• 10/17/2013 If an Equipment attached to a creature becomes a creature, it becomes unattached. An Equipment that is also a creature can’t equip another creature.
• 10/17/2013 Multiple instances of deathtouch or lifelink on the same creature are redundant.
