For a card that says 'Target a gear. Its controller may kill it' then 'Draw 1' - do you need to kill the gear to draw, and can you play it without controlling a gear yourself?

Ruling: You can play the card as long as any player controls a gear (including your opponent's). You draw 1 card regardless of whether the gear is killed or not.

Sequence:

• Target any gear (yours or opponent's) when playing the spell
• The gear's controller chooses whether to kill it during resolution
• Draw 1 card regardless of the choice made

Nuances:

• You cannot play the card if no gears are on the battlefield at all
• The draw effect is independent from the kill effect (separated by a full stop/period)
• You can target your own gear and choose not to kill it, still drawing the card
