Can Salvage be played when there is no gear in the game, given the new errata changing it to "You may kill up to one gear. Draw 1." and the rule allowing "up to" effects to choose zero targets?

Ruling: Yes, Salvage can now be played even when there is no gear in the game. The "up to one" wording allows you to choose zero gear as targets, play the card, and still draw a card.

Sequence:

• Play Salvage
• Choose zero gear as targets
• Draw 1 card

Nuances:

• This only applies to cards with "up to" wording; cards without "up to" wording still require valid targets to be played
• The errata was specifically designed to prevent Salvage from being a dead card when no gear is in play
