Why Fluffals and Shaddolls?
First the typing on the Fluffal monster give easy access to the shaddoll fusions like
El Shaddoll Construct (
Fluffal Wings), and
El Shaddol Shekhinaga(
Fluffal Cat, Dog, Rabbit, etc) and even
El Shaddoll Winda (
Edge Imp Chain). The Typing is nice but what really matters is that most Several Fluffal monsters have effects that trigger off ANY fusion summon or benefit from being in grave. At a bare minimum the Shaddoll engine gives Fluffals some extenders/starters to help guarantee to break a board. At the maximum Shaddolls are a ridiculous value engine that create insane pluses off of every fusion. P.S. you can mill shaddolls off toy vendor for there effects.
How does the deck Play?
The deck plays like a build-a-bear combo, every hand is different but the different value engines all lead up to the same thing: fusion summoning cards like
Frightfur Tiger, Frightfur Kraken, or El Shaddol Construct to clear the way and then Fusion summoning some more and swinging for game. A much simplier way to clear the board for your OTK's are with cards like
Dark Ruler No More or
Super Polymerization. Super poly has crazy synergy with Shaddolls as just 1 Shaddol + any monster is a fusion, and the deck also plays
Mudragon of the Swamp as an additional target, but another great use of Super poly is for a quick play fusion summon during the battle phase with your own monsters for extra attacks. If you don't draw a super poly or a dark ruler the deck can play around negates simply by playing more cards than your opponent can respond too. Cards like
Shaddoll fusion,
Frightfur Patchwork, and even just a basic
Polymerization must be stopped by and opponent or they risk losing board state or card advantage.
What Weaknesses Does the Deck Have?
Nibiru, The Primal Being. Consistency, the deck is actually very consistent on its ability to get out a board that can OTK, but how good it is at breaking boards varies. Simply you wont have big cards like Super Polymerization or Dark Ruler No More in hand every game. However you can search Super Poly off
Predaplant Verte Anaconda and set up for a easy Mudragon by using anaconda's effect to make a monster Dark, its just a hard card to make at times. Lastly this deck really doesn't do great going first.
What to do Going First?
Try to make
El Shaddoll Winda like your life depends on it. Most decks struggle to out winda and even if they do it slows them down. My side deck plays some more Shaddoll monsters to increase the chance of making a decent shaddoll fusion. Outside of that just try and use some of your searchers like
Edge Imp Chain,
Fluffal Dog, and
Frightfur Patchwork to set up for your next turn.
