DD Sprite is a Fairy type Tuner with 0 attack and 100 defense of the Light attribute and is Level 1.  Being a Fairy is quite workable, and being a Tuner is never a bad thing.  Ironically, you are likely just going to use this as a Tuner as opposed to using its effect.
 
You can Special Summon DD Sprite by removing from play a face-up monster on your Field.  If you do, return the removed monster to the Field during the next Standby Phase.  I assume this would be your opponent's if only because it doesn't say "yours".
 
I don't see much use for that ability, unless you're trying to say...free a monster of yours from a Trap or effect of some other card, maybe return the attack score of a monster you control to normal?

D.D. Sprite

She's fat. Removing one of your monsters? Not fun, but it comes back next turn. But what's the point, when you're just summoning a Level 1 Tuner? Why not summon the Sprite instead of some other monster? Maybe you're desperate for Catastor or something. I'd rather use a better Level 1 Tuner, like Glow-Up Bulb or something.

Here we are looking at D.D. Sprite. It is a one star, 0 atk, 0 def, light fairy tuner. You can special summon it by removing from play one face up monster. And it comes back during the next standby phase. This card seems ok, but it has some obvious drawbacks. It’s a one star, so formula synchron abuse is easily available. Now one of the biggest drawbacks to this card is that it brings the removed monster back on your opponent’s standby phase. This card takes a lot to use to its fullest, but it seems like excellent sac fodder for that monarch in the hand.

D.D. Sprite is terrible card. At first glance, it may seem like it could have some neat combos, but the card removed to summon it is not returned to play if D.D. Sprite is not on the field during the Standby Phase. That pretty much removes any possibility this card could be useful.

If you really want, it could be used with D.D. Survivor or D.D. Scout Plane, since those will come back anyway. Or maybe D.D. Destroyer could work. That's about the best it can do.

Traditional: 1/5 It's a LIGHT for Chaos, I guess?
Advanced: 1/5 The card is just awful.
Art: 1/5 It's also dumb looking.

D.D. Sprite

This is an interesting little card that got my attention form day one of Storm of Ragnarok's release. He is a level 1 LIGHT Fairy Tuner with 0 ATK and 100 DEF. I don't know why it has 100 DEF, maybe because he can wack you with his foot or something, but those are pretty bad stats, the only redeeming quality to them is that he is a Tuner.

The effect is simple, you remove from play a monster you control to Special Summon it and during your next standby phase it comes back. This would be great, except that for the removed monster to come back, D.D. Sprite needs to be face up on the field or it stays removed. The rulings on this card destroyed any playability it might have had in a standard competitive deck.

However, a deck that generates a lot of tokens could use this. That new compass card, Scapegoat and Dandylion come to mind readily and lots of free tokens generally means that you can do some Synchro Summoning with this guy. The biggest combo I saw with it was to get a bunch of tokens and then remove one of them for this guy and then play that one card that makes all monster's ATK to 0 when you remove a card from play. Trading your expendable tokens for SYnchros and power cards seems good while at the same time making them useless for battle.

Other than that expensive and risky combo, there is not too much you can do with this card besides remove from play like D.D. Scout Plane or D.D. Survivor. You CAN color his hair so that it is just like Yusei though.
