Does Karma's ability trigger when recycling a rune to pay for Sett legend's ability, and if so, can the buff be given to the unit being recalled?

Ruling: Karma's ability does not trigger when recycling runes to pay for Sett legend's ability because runes are not cards.

Nuances:

• Karma's card text specifically states that runes are not cards
• For rules purposes, "cards" always refers to main deck cards, which runes are not
