Shooting Quasar Dragon.

Shooting Quasar Dragon
4000/4000
12 Stars
Dragon/Synchro/Effect

1 Tuner Synchro Monster + 2 or more non-Tuner Synchro Monsters
This card cannot be Special Summoned except by Synchro Summon. This card can attack a number of times during the Battle Phase equal to the number of non-Tuner monsters used as Synchro Material Monsters. Once per turn, you can negate the activation of a Spell, Trap or Effect Monster's effect and destroy it. When this card is removed from the field, you can Special Summon 1 "Shooting Star Dragon" from your Extra Deck.

A Strong, Synchro, Dragon that replaces itself when it is destroyed.
What was my first impression when I saw that card? OMG want.
The summoning conditions for him are not hard to acomplish, but not THAT easy either (maybe in a Ritua fish deck, so yea).

Junk Doppel decks can bring him out since they can just spam Librarians and Formulas in one turn.

Ryko in the graveyard One for One, junk Synchron and Foolish Burial.
- Normal Summon Junk Synchron, revive ryko and synchro for Librarian.
- Foolish Dandylion, One for One spore and make a Formula Synchron with one Fluff Token to draw 2 from Librarian and Formula.
- Remove Dandylion to revive Spore and synchro with the other Fluff Token for a second Librarian and draw 1 more.
- Synchro both Librarians + Formula Synchron for Shooting Quasar Dragon.
(there are other ways of bringing him out in this deck, what I did was just an example)

In total you used 4 cards in your hand + 3 cards you drew + Shooting Quasar, making up with the hand loss.

Ritua Water with Ritua Beast and Ritua Erial. 

- Have Treeborn Frog, Fishborg Blaster and Ritua Erial in your graveyard and a Ritua Beast in your hand.
- Standby Phase Revive Treeborn and then in Main Phase Normal Summon Ritua Beast to Revive Ritua Erial.
- Dump a card for Fishborg Blaster and synchro with either Beast or Erial(doesn't matter which first) for T.G. Hyper Librarian.
- Dump Another for Fishborg and synchro with the other one for a Second Librarian and draw 1 from the first Librarian.
- Dump another Card for Fishborg Blaster and synchro with treeborn for Formula Synchron just to draw 3.
- Synchro all three for Shooting Quasar.

In the end you used Ritua Beast + 3 cards from your hand for Fishborg Blaster and you drew 4 from Librarians and Formula.

There are many other ways of bringing Shooting Quasar Dragon and expect this card to wipe asses when he is on the field.
