Hi, I like fusions. Predaplant got some nice support, and so did Fallen of Albaz, so I slapped them together with a couple Despia, Dogmatika and Shaddoll cards and called it a day!
The main deck is just some standard stuff really. There's 2 Orphys Scorpio, 1 Darlingtonia Cobra, 1 Chlamydosundew and 1 Spinodionaea(for counters), plus 2 each of the new pends Triantis and Bufollicula and 2 Byblisp from Predaplants, along with 2 copies of Predapractice to help board presence and pull more to hand, 1 Predapruning, and the only traps are 1 each Predaplanet and Predaplanning. They have useful on board effects but also offer something while in grave, planning being a destruction and planet being another fusion card. The Shaddoll package is simple, 1 each of Wendi, Ariel, Beast, Squamata, Dragon and Hedgehog. Squamata gives you more mill, Hedgehog pulls one to hand, Wendi summons one from deck, Beast draws a card, Dragon destroys 1 Spell/Trap and Ariel banishes 3 cards from either grave, and since Shaddolls like going to grave, you'll be activating their effects a lot. I also have one copy each of Shaddoll Fusion and El Shaddoll Fusion. El Shaddoll is a target to add to hand when you Nadir Servant El Shaddoll Apkallone since you can set it and quick fuse Winda on the opponent's turn without having to discard for Super Poly. Dogmatika Ecclesia and Fleurdelis are simple staples and offer Light attribute necessary for both El Shaddoll Construct and Albion the Branded Dragon without having to use your extra deck for them. I chose to run 1 Dramaturge of Despia because I like its recursion and board presence, plus it offers a negate, and Aluber gives additional search for Branded Fusion and the other spells like Branded Opening and Despia, Theater of the Branded. The real stars of the show are 1 Springans Kitt offering even more search, and 2 Fallen of Albaz. I run 2 because I've found myself running into trouble using him in hand for a fusion, then trying to use Branded Fusion to pull from deck. There is a third(technically) by using Albion the Shrouded Dragon, but getting it into position to make it count as Albaz for a fusion has proven troublesome, so I tend to use it to send 1 Albaz to grave and swap Albion for something. The remaining cards are Foolish Burial to get Byblisp to proc, 2 Polymerization, 1 Super Polymerization(removal is always nice) 1 Raigeki, and 1 Monster Reborn. So I'm a little scrubby and I like Monster Reborn, sue me.
The Extra Deck was harder since there were so many good options I had to choose between, but I ultimately decided at base, it's purely fusions. There's so many cards that lock you into fusion only, I did a test hand and ended up with 4 of those restrictions layered on top of each other. Predaplant Ambulomelioides is EXTREMELY integral because it can be fused in hand, search a Predaplant on summon, tribute itself or another monster to then summon another one, and I like to use it to tribute another low level monster, summon Chalmydosundew, then use sundew's effect to fuse into Dragostapelia. Dragostapelia is a very good card because it has a quick effect predator counter stack, and a continuous effect where anything with a predator counter has it's effects negated. It spreading counters so easily is very beneficial to 2 of this deck's boss monsters, Triphyoverutum and Starving Venom Predator Fusion Dragon. Triph gains attack equal to every monster with a predator counter's attack so it can skyrocket very easily with Drago, Triantis(if used for a fusion, it applies counters equal to the number of monsters you control) and Spino. In addition, once a turn, Triph can negate 1 Extra Deck summon from your opponent and destroy the monster. SVPFD on the other hand can tribute any monster with a predator counter to negate something your opponent is doing. Any card or effect (that can be responded to) is just negated, simple as that, so if you can manage Drago and SVPFD, which this deck absolutely CAN do, you get 2 negates with this combo. Chimerafflesia is an extra I added, but it's still useful because its requirements mean you can use most of the Shaddolls and a Predaplant and again, does not need to be on board! For Shaddolls, it's just Construct, Apkallone and Winda, that's really all you need. Or at least, all I've ever seen people use from Shaddoll. Construct destroying any special summoned monster in battle before damage calc, Winda locking players into 1 special summon each turn while it's on board, and Apkallone giving a search when sent to grave, and the negate on summon is a nice benefit if you do decide to summon it. I run Despia Quaeritis because it's got flexible materials, and the quick effect dropping non-fusion and low level fusion monster attacks to 0 is nice since this is a fusion deck. I also run Masquerade, the Crimsongleam Dragon because it's more options to put pressure on your opponent if you go first, causing burn for every play they make. I use 1 Albion the Branded Dragon for using with Branded Fusion to send a Dogmatika to grave, so I can then summon Lubellion with it's effect by banishing the Albaz I sent to grave and a dark monster, which then ideally leaves me a Shaddoll in hand I can discard, or one in grave that I then fuse into Construct. I've done a lot of tests on running optimal lines for this, and this gives you three fusions on board, and only needs a little grave setup prior. I have Titaniklad because sometimes damage is necessary, but it doesn't do a whole lot else other than maybe be a Nadir Servant target or even a Super Poly choice. Mirrorjade is nice for its quick effect non-targeting banish and is a good option if you don't want to make a board full of fusions and only want a couple, both Albion and Lubellion lead really nicely into it. This just leaves Starving Venom Fusion Dragon and, it's just good. Any 2 Dark monsters on field so it is a great Super Poly target to remove troublesome boss monsters like Accesscode Talker, Borrelsword Dragon, Raidraptor Ultimate Falcon, Destiny HERO Destroy Phoenix Enforcer, all sorts of nasty stuff just so happens to be Dark, and if Starving Venom gets destroyed, it'll destroy any and all special summoned monsters on your opponent's field it can.
I wanted this deck to have options, and usually, thanks to all the search, I consistently get 3+ fusions on board. Out of all the tests, maybe 5 duels I ended with 2 or fewer monsters turn one, and the remaining like, 40, i've had at least 3, most often 4 monsters on board, and this deck can even pump out a completely full board with Winda, Construct, Drago and Dramaturge.
Also pls no bulli, this is my first attempt at seriously building a deck, I've just been netdecking until now but the new support was too juicy for me to not experiment with. I don't use side decks so I just slapped in whatever.
