How to Farm Quattro

Strategy

• Summon Loading... as quickly as possible, use your Lunalight effects in order to get enough Monsters to be able to summon Sabre Dancer (Don't Forget His Xyz Monsters give you additional material)
• Destroy Loading... if you can, as it has the potential to have a devastating effect on the board (although his AI doesn't seem to use it's effect often if at all)
• Cycle through your deck with your Lunalight cards as quickly as possible
• Summon a second Sabre Dancer before your Last Turn (You can also Summon a third by using one of your first two as material, letting you use Sabre Dancer's effect in GY)
• WARNING He has Loading... , try to save your Loading... for the End Phase (until he uses it), and Never have 1 card left in your Deck during his Main Phase, you don't want him using it and force you to Deck Out!

Last Turn

• Use your Loading... and Loading... effects to boost your Lunalight's ATK.
• Normal Summon Loading... and use Loading... and Loading... on it.
• Enter Battle Phase, Attack Quattro Directly for Victory!

Strategy

• Can be run Skill-less. Skills that can be run include Draw Sense: LIGHT , Draw Sense: FIRE , Draw Sense: EARTH , and LP Boost Alpha
• Your ideal opening is to either summon Loading... (searching Chocolate) or Loading... (Discarding Berry to Draw a card), otherwise you want to attempt to stall with either Loading... or Loading...
• Your Goal is to get 2 Loading... on the field (by using the effects of Berry, Chocolate, and/or Apple) in order to draw through your deck with their effects.
• When applicable, use the redirection effects of your Magician Girls to protect the Chocolate Magician Girls, otherwise draw through your Deck as much as possible with Loading... and Loading... (Make sure you pass each turn with either 2 Chocolate Magician Girl or 1 Chocolate with a Berry in Graveyard and another Chocolate in Deck if possible)
• Be Careful with his one copy of Loading... ! Don't pass the turn to him when you only have 1 Card left in deck, and always make sure to keep a disposable card (like a Spellcaster) in hand just in case he activates it.

Last Turn

• Note that the final Turn doesn't necessarily need to occur when you're out of cards, if you have the means to Xyz Summon a Rank 4 and Loading... with over 10k ATK, that can make up for any Duel Assesment you would be missing (your mileage may vary, of course).
• If Trey has a set backrow or a Loading... , Xyz Summon Loading... and use its effect to Destroy it. Otherwise Xyz Summon your Loading... (As it's guaranteed Prismatic), Loading... (As it's a Spellcaster you can use Loading... on), or Loading... (if you have two Loading... ), and get the bonus Duel Assessment for Xyz Summoning.
• Activate Loading... to Fusion Summon Loading... with 5 differently-named Spellcasters and use its effect to wipe the Field.
• Activate both Loading... on Quintet and Attack Directly for Victory
