Introduction

Melffy is a new archetype in Rise of the Duelist, releasing in August this year! People are using beast-type support to help the deck work. For example, Obedience Schooled or Ayers Rock Sunrise.
However, it can be a bit lacking at times.

When all seems lost for our adorable friends, a shadow looms over the distance and offers its hand. None other than Crystron Halqifibrax! The forest critters gladly accept Fibrax's offer and thus Comboffy is born.

Let's take a look and see just how the deck ticks!

Part I: The Melffy

Melffy plays with returning themselves to the hand to use their effects. All of them focus on different utilities involving level 2 or lower beasts. Puppy summons from the deck, Cathy adds one to your hand, Pony recycles, and Fenny summons from hand. 

With this in mind, monsters like Kalantosa, Mystical Beast of the Forest and Hop Ear Squadron fit in, offering strong forms of disruption.

For the Xyz monsters, Melffy of the Forest is the main go-to, searching any key piece at a given moment. Mammy is lackluster in the combo version.

The two spells are nifty one-ofs for their utility, and Time has decent disruption uses.

Part II: The Combo

You may be wondering how the deck even makes use of Fibrax when it has no native tuner.

This is where generics come into play. Tour Guide of the Underworld and extenders offer a lot of bang for your buck. This pairs up with cards like Crusadia Arboria, Cherubini, Sangan, and most importantly, Linkross.

Playing a hefty amount of extenders can help you power through interruption and make the most of your hands.

The requirements are simple, only needing a Link 2 and a way to a tuner that can bring itself out. Cards like Psychic Wheeleder, Super Hippo Carnival, Melffy Tag, Cockadoodledoo, and Emergency Teleport can help reach this goal if TGU doesn't show up.

Part III: In-Depth Analysis

Example: TGU Start

• Normal Summon Tour Guide to get Sangan. Link into Cherubini, and search Arboria off Sangan.
• Use Cherubini's effect to send The Phantom Knights of Silent Boots and banish it to add Fog Blade to your hand. Special Arboria from your hand. (it doesn't activate).
• Make Linkross, summon two tokens, and go into Crystron Halqifibrax.
• Halq then places Jet Synchron into play. Make Formula Synchron and draw 1. Revive your tuner with its effect and make the second Formula to draw yet again.
• Lastly, overlay both of them to get Melffy of the Forest! Don't forget to use its effect to search, Puppy is the best one if you don't have it yet.

Similar openings like Super Hippo Carnival + Sangan can get you here too. There are also other paths to explore if you look hard enough! For example, TGU + any extender leads to a potential I:P Masquerena!

Where does that leave us? At the bare minimum, it's Fibrax, Melffy Puppy, the Xyz plus a Fog Blade.

Let's take a look:

1. On-demand targeted destruction that can be made hard to answer by queuing Forest as CL2 (Puppy -> Kalantosa)
2. Forest's negation
3. Fibrax tagging into Desert Locust to rip a card, then climbing into either PSY-Framelord Omega or Borreload Savage Dragon. (one negates, one adds another hand rip).
4. Fog Blade 

We still have other cards in our hand especially with the free draws. That means more Melffys to use or other cards to stay ahead in the game! 

For example, having Melffy Cathy search out Hop Ear Squadron to go into Herald of the Arc Light which you can protect with all your other tools at hand.
Melffy Fenny lets you make use of Kalantosa in your hand for more destruction! Pony can get it back too.

Part IV: The Backup

Melffy has a good amount of wiggle room to play more defensive cards in case the combo goes wrong.

They hop out of your hand during the End Phase, so it's not like you're utterly helpless either! But still, support is always appreciated.

Paleozoic traps are a nice fit for removal options, as well as being level 2 to work with both Hop Eared and Locust for synchro plays. The deck can also make Opabinia and get more of them should you see one in your opener.

They're a nice plan B that goes hand in hand with what you're trying to do. Great to have as well in case of cards like Nibiru, Dark Ruler No More, or Sphere Mode to ruin your day.

Sangan also offers potential hand trap searching so cards like Ash and Ogre can fit right in. (Ghost Ogre is also an emergency teleport target!)

Part V: The Experimental Deck and Conclusion

This sample deck should be a good starting point for what the deck aims to achieve!

Hide and Seek is usable if you can find the space for it. Carboneddon package is a nice contender too for it makes Cherubini a stronger play enabler.

Lastly, more research into Phantom Knights and Isolde plays are worth looking into. After all, we've only tackled the surface of what Combo Melffy is capable of. Tear Scale is soon to be released and offers a whole lot more than you might expect!

While this won't be the new Synchro Eldlich, it's an interesting deck with great aesthetics and unique gameplay. The control build is also fine as well if that's your preferred cup of tea.
