Does using Sabotage to recycle a card from an opponent's hand into their deck trigger Karma's effect when you control Karma?

Ruling: No, using Sabotage on your opponent does not trigger your Karma. Only recycling cards into your own deck triggers Karma's effect.

Nuances:

• Only the owner of a card can recycle it into their deck
• If your opponent uses Sabotage on you while you control Karma, you do get the buff since you are recycling into your own deck
