In the original Kamigawa block spells had Arcane as a subtype, and you could pay the cost of a card like this to add that cards effects to another card. For example you could splice this onto Kodama's Reach, keeping the Goryo's revenge in your hand.

Thank you! That's an awesome mechanic! I see why it's not used heavily, I'm sure it can get out of hand
