You can choose a number from 1 to 3 cards, then send that many cards from the top of your Deck to the GY; increase this card's Level by the number of cards sent to the GY this way, until the end of this turn. If this card you control is destroyed by an opponent's card and sent to your GY: Gain 1500 LP. You can only use each effect of “Cupid Volley” once per turn.
Activate the effect of Mystic Piper to draw a card. And if you draw Cupid Volley which is a level 1 monster, you can draw another card. Where Arf Thou can be used to search out Cupid Volley which you can then immediately summon to use as a Synchro material by changing it's level depending of what you need.
Cupid Volley is a level 1 LIGHT Fairy-type which allows you to use Court of Justice to special summon another Fairy monster from your hand. You can then adjust the level of Cupid Volley to whatever you need and use her with the monster you special summoned to Synchro into a new monster.
Lightsworn is an archetype that love to mill their own deck to gain effects and advantage off of it. Cupid Volley can help them mill the deck to trigger effects. If you happen to mill Wulf, Lightsworn Beast you can special summon him and use him as Synchro Material along with Cupid Volley.
Lol, this is from the most current main box in the TCG. It's called Cybernetic Horizon. Yeah, lately they have been designing some modern cards with Duel Links in mind. Interesting cross-promotion imo.
