Does Karma Channeler's ability trigger when you pay recycling costs for runes?

Ruling: No, Karma Channeler does not trigger when you pay recycling costs for runes. Runes are not cards and Karma received errata clarifying she only cares about Main Deck cards, which runes are not part of.

Nuances:

• Karma Channeler will trigger off her own Vision if you recycle the card itself
• Recycling runes never triggered Karma, but the errata made this more clear
