Spell Economics (DR2-EN202)

[duel]

Card Text: You do not have to pay any Life Points to activate a Spell Card.

Rulings
While "Spell Economics" is active, you don't have to pay Life Points to activate a Spell Card (place it face-up on the field), but to activate an effect of a Spell Card, like "Archfiend's Oath", you still have to pay.
Only the controller of "Spell Economics" gets its effect.
You have to pay for "Chain Energy" even if you control "Spell Economics".
You pay the 500 Life Points to restore "Horn of Light" to your Deck even if "Spell Economics" is on the field.


I am interested, if i have to pay for the Activation of "Autonomous Action Unit" and for "Premature Burial" after activation of "Spell Economics"? I think - no.
Also, i think, the Effect of "Spell Economics" will work generally with Spells, their Name begins with "Pay xxx Life Points ...".
Am i right?

Spell Economics will negate the Life Points payment for cards such as Premature Burial, Autonomous Action Unit, Toon World, etc. If you pay the Life Points when you put the card on the field and activate it, then Spell Economics will negate the Life Points payment.

It will not negate the Life Points payment of cards that are already face-up on the field (usually Continuous Spell Cards), whose effects you can activate at will or activate repeatedly as a continuous cost (Card Shuffle, Messenger of Peace, Inspection, etc.).

So Spell Economics negates the original Life Points cost of a Spell Card, and not any later ones.
