You can only activate this card when you activate one of your Normal Spell Cards. Discard all the cards in your hand to the Graveyard. The effect of this card becomes the same as the Normal Spell Card.
I feel this card was overlooked upon its release, but now that Graceful Charity and Delinquent Duo are returning from the Ban list i feel this card will see alot of play, after thinking briefly of what Would be copyable, Remember Serial spell only copies the effect not the cost, but you must discard at least one card from your hand,
Pot of greed, Draw 4 cards
Graceful charity, draw 3 discard 2 draw 3 discard 2,
Delinquent Duo, pay 1000, discard 4 cards from opponits hand
Nobleman of Crossout, remove 2 opponits f/d monsters
Monster...
