Sweet and tasty, but ever-so-bad for you, these dessert-themed demons make up a stark contrast to Madolches because they don't recover themselves . . . in fact, they rely on each other to recover.
Now, the archetype is heavily based on spamming themselves, with all manner of self-Summoning effects to use to just plop them down on the field either from the hand, or reviving themselves with proper field setup. What you might notice, though, is that each Main Deck one has exactly 3 effects: One each borrowed from a Main Deck monster of their Level from the GX, 5Ds, and ZeXal eras. What thieving demons, can't even get their own effects! Generally, though, one effect will be built around bringing itself to the field, and another will be based around consistency in some way . . . and, given the subject matter, quite a few help with recovering each other once you have setup going. Yes, the Level 7 one does, in fact, rip off a Dragon Ruler with one of its 3 effects.
However, you may have noticed that most of the extra-exploitable effects, necessary in the modern day, fall just outside the range of these guys. What is the solution? The backrow lineup here is . . . intense. While you have some pretty sweet consistency effects, more revival, an Arc-V era level of god-powered Field Spell, and even an archetypal Shaddoll Fusion variant (more on that later), the real kingpin here is a Continuous Spell that makes them an ED spam Deck that can effectively go second with no real punishment
, breaking your opponent's board in the process of making their own and giving you a monster search or recoup once per turn.
But, of course, that power card only goes off if you can make one of their archetypal ED monsters. Certainly those are horrible to compensate, right? Oh, you wish. While they aren't incredible in their scope (their Synchro can't hold a candle to something like Siegfried or Clear Wing), they do have one or two monsters per Summon mechanic, and each one is tolerable going on good, rewarding you for the effort of Summoning them, or making a mockery of your opponent given the lack thereof. Interestingly, the best boss they have is their big boy Fusion, not just because it carries negation from both the IRL and anime versions of Quasar (the latter being "permanently negate the effect of any card on the field every time I battle") on a double-attacking body, but because its Materials turn your Shaddoll Fusion copy into "Foolish one of each different name in your Deck, have fun winning the game now".
However, they do have one exceptional, super-noteworthy weakness, making them tricky to Deckbuild for and somewhat prone to bricking: backrow negation. Remember, their real power cards to make the Deck capable of even making all their bosses and crushing your opponent beneath your thumb are in their S/T lineup. Siegfried, mentioned above, can utterly crush this Deck if its effect is timed properly, and if a Six Sam player can drop multiple Shi'en then you might as well scoop. Be cautious.
