Have been playing this deck for years. It can very easily steal games and work through multiple negations if you sequence your cards well.
Card by card (read all monsters in decklist first):
Key phrases:
Soft once per turn: can use the effect multiple times in a turn, once per copy of card.
Playmaker: gets the combos started
Extender: keep the combo going
Main Deck Monsters:
Lunalight Kaleido Chick [Playmaker/SOFT ONCE PER TURN]
This card is mandatory at 3. It not only sets up most of your plays but also has two incredible effects and one relevant effect. The first lets you send a lunalight monster from deck or extra, which in most cases will be a yellow marten (if you did not open one), panther dancer (to setup wolf for the current turn or next), or crimson fox. This send to grave is a COST (be careful of effects that banish any card sent to grave; you won't be able to activate the effect at all). On master duel a lot of people make the mistake of negating kaleido chick to turn off the name change but that’s not what she is used for mostly. If you do get the name change and can make leo dancer, then go for it.
The other important effect is the on banish. Once kaleido chick is banished you can wrap up the game as your opponent wont be able to activate cards or effects during the battle phase. You banish chick two ways here; either by wolf to fusion summon or by allure of darkness.
The final effect is the add back of poly. Don't discount this. There are times when you can ditch the poly for the perfume or serenade dance and then get it back later.
Lunalight Wolf [Miracle Fusion/Pierce Access/SOFT ONCE PER TURN]
Wolf is there to make your fusions using the grave. Make whatever the situation calls for. Since you don't always need to normal summon, you can normal summon the wolf after using its effect and bouncing it to hand with yellow marten.
Lunalight Tiger [Playmaker/Rank 4 Maker/SOFT ONCE PER TURN]
If you do not open with tiger, find a way to access it. You can do this a couple of ways like adding with tenki or perfume, sending to grave with chick and using black sheep, special off serenade dance and bouncing with yellow marten, etc. Because tiger is a soft once per turn you can use the effect to special from grave as many times as you can play the card.
The most common use: activate in scale, special a lunalight, yellow marten in grave or hand to bounce tiger, and reactivate tiger to special another lunalight.
This was abused in the past which is why its a 1 currently in the tcg. Tiger's other effect is its on destruction special from grave. This does work if it is destroyed in the scale and can be combo'd with daruma doll to pop back row while getting back any lunalight from grave (usally chick).
Lunalight Yellow Marten/Emerald Bird [Extenders]
Yellow marten: You can bounce your cards to reset them and be used as easy material for a rank 4. You can get the sent to grave effect by using her for fusion summoning, the effect Redoer, sending off serenade dance, or for emerald birds draw. What you search is mostly lunalight fusion but if you have a way to get serenade dance to the grave you can go for that too.
Emerald bird: The send to draw helps setup and can bait out certain hand traps. You can also get the sent to grave effect with the same methods as yellow marten. Bringing back a banished kaleido chick will let you send another lunalight to grave or you bring back yellow marten to keep it in rotation.
Lunalight Black Sheep: Add poly to hand, bait out negates, if used for a fusion you can add back your wolf/tiger in grave or extra deck.
Lunalight Crimson Fox: Changes to atk of opponent’s monster to 0, gives targeting protection while in grave
Lunalight Blue Cat: Doubles the original atk if special summoned (will not include bonus increases like tenki), has a floating effect. The early builds ran multiple because you could summon blue cat off blue cat then go into tiger which could summon back the blue cat effectively make an attack block chain. I suggest beginners run 2 otherwise 1 is fine.
Lunalight Purple Butterfly: Gives a lunalight 1k atk, usually sent off kaleido chick, can special the blue cat/wolf/bird/chick in hand by banishing from grave.
Spells and Traps:
Tenki: Search any lunalight outside wolf
Allure: Helps draw and can banish kaleido chick
Foolish Burial Goods: Sends perfume or serenade dance, can bait out hand traps or negates if played first
Harpies/Lightning Storm: Get rid of back row or problematic monsters before going full combo
Luna Light Perfume: NOT a lunalight card, monster reborn for the archetype, can get cards from hand to grave but is a COST, adds any lunalight from main deck (mostly searches wolf), NOT once per turn.
Lunalight Fusion: The shaddoll fusion of the archetype that can send from extra deck, can bait or be negated by ash blossom
Monster Reborn: Bring back key pieces
Called By The Grave: Stop hand traps or get rid of important monsters in grave
Lunalight Serenade Dance [Playmaker]: Can send a card from hand to grave, special usually kaleido chick from deck, can play a second copy if needed
Extra Deck:
Lunalight Fusions: Make Leo Dancer or whatever the situation calls for. You can go into Sabre dancer as a first turn play to setup its grave effect or use it later as a finisher.
Rank 4s:
Tiger king: Access to tenki as well as board wide negate.
Time Thief Redoer [Extender/Best Friend]: His effect sends the materials to grave which triggers the lunalights. Most often you will be detaching yellow marten to search for lunalight fusion. Is also a dark monster and can be used to make starving venom if needed.
Number 41: Bagooska: This card is plan B if you cannot win the game with your current setup. Keep him in defense as long as you need to build up resources and make sure to put him in atk before fusion summoning.
Abyss Dweller: Good for times where you have to go first

Last tip is to pay attention to what order you play your cards and how the opponent reacts. Hopefully this, along with my replay videos, will help newer players get more familiar with the archetype.
