Once per turn, you can destroy a monster in your hand or that you control with Fire King Island and then add a “Fire King” monster from your deck to your hand or, if you control no monsters, you can Special Summon 1 Winged-Beast FIRE monster from your hand.
The first part of the effect of the Field Spell allows you to trigger Yubel’s effect and Special Summon Yubel - Terror Incarnate from your hand, Deck or Graveyard while also adding Fire King Avatar Yaksha or Fire King Avatar Barong to your hand, whereas with the second part you would be able to get Sacred Phoenix of Nephthys on the field right away.
This is the combination of cards that you want to start with: My Name is Yubel allows you shuffle back into the Deck one of the two other forms of the monster and add a copy of the first form to your hand, making the deck more consistent.
If you did not start with Fire King Island, don’t worry, you can still activate Yubel’s effect: when Yaksha is destroyed by battle or card effect and sent to the Graveyard, you can destroy a card in your hand or that you control.
Yaksha’s effect is not mandatory, so you don’t have to activate it, but you can use it to send Sacred Phoenix of Nephthys to the Graveyard and destroy all Spell/Trap Cards on the field when it’s revived by its own effect on your next turn.
You can’t activate Fire King Island’s effect unless you have a “Fire King” monster in your Deck to add to your hand. Barong has the exact same stats as Yaksha and, just like it, it can be Special Summoned from your hand when a face-up “Fire King” monster you control is destroyed by card effect.
If Barong is destroyed by card effect, you can add another “Fire King” card from your deck to your hand during the next Standby Phase, including the Field Spell.
Sacred Phoenix of Nephthys Special Summons itself from the Graveyard during your Standby Phase after it was destroyed by card effect, destroying all Spell/Trap Cards on the field, whereas Yubel - Terror Incarnate destroys all monsters on the field, except for itself during your End Phase: these two cards can completely lock your opponent, wiping out everything that is on the field every single turn.
Without Sacred Phoenix of Nephthys this deck would have trouble dealing with Amazons as they can just banish Yubel and Yaksha with Amazoness Onslaught, so it’s pretty important to have it, even though going back to Dawn of Destiny to get three copies of it is not advised.
The best thing about Yubel is easily the fact that, when it is destroyed by card effect, it floats into its next form, but there is to say that, among all three, the “final form” is the most underwhelming. Sure, you can attack your opponent’s monsters, deal effect damage equal to their attack and then destroy them, but it just doesn’t compare to blowing up all monsters on the field.
Since Sacred Phoenix of Nephthys is going to destroy your own Spell/Traps too, you can’t really run common Battle Traps like Wall of Disruption or even cards like Paleozoic Canadia because you run the risk of wasting them; Sphere Kuriboh is great in this deck because it’s a Hand Trap, your opponent can’t do anything about it Hey, Trunade! or Cosmic Cyclone.
This Skill makes the deck a lot more consistent, making it easier to start your main combo. You obviously don’t want to Special Summon Terror Incarnate or Ultimate Nightmare from your hand and My Name is Yubel allows you to shuffle them back into the Deck.
|You can tribute this card to add Fire King Island to your hand; it’s not a bad choice, but you are still likely wasting your Normal Summon to get it on the field and a Floodgate Trap Hole or Paleozoic Canadia would easily stop it.|
|This Continuous Trap can revive Yubel, it does have synergy with it, but, since the deck runs Phoenix, it might not be worth it.|
Vampire are usually very fast to set up, but their only way of getting rid of Yubel is through Vampire Kingdom’s effect, which is limited to once per turn. Even if Terror Incarnate is destroyed, you would still get to summon Ultimate Nightmare and attacking into Vampire Vamp, Vampire Grace or Vampire Scarlet Scourge with it and causing pretty substantial damage.
Wiz, Sage Fur Hire can negate Fire King Island, Dyna, Hero Fur Hire can banish Phoenix from the Graveyard and Donpa, Marksman Fur Hire can destroy Terror Incarnate, but you still would get Yubel - The Ultimate Nightmare on the field. Fur Hires are quite problematic, but they not impossible to beat: Sphere Kuriboh can save you from an OTK while you set up for Terror Incarnate; even Fur Hires have trouble recovering from a full board wipe.
As I said, Amazoness Onslaught can be very problematic, but Phoenix should be enough to deal with it; the protection the Amazoness Queen provides for Amazoness monsters is pretty irrelevant since Terror Incarnate can destroy them with its effect and you generally don’t have to fear Amazoness Swords Woman attacking into your monsters since the one that is going to stay on the field has 0 ATK.
Not the easiest matchup, but, once Phoenix gets rid of the Continuous Trap, it should be pretty easy to win.
Masked HEROes tend to try and end games very quickly, but they don’t usually have monster removal aside from Treacherous Trap Hole, so their best way of getting rid of Terror Incarnate would be to target it with Forbidden Chalice and then attack it while its effects are negated.
Again Sphere Kuriboh is very important: your opponent has no way of knowing you have it as long as you are not giving it away.
Spellbook of Fate can banish Terror Incarnate or Phoenix, if your opponent wants to set cards freely, and, even if you destroy Silent Magician, its effect would Special Summon the Silent Magician LV8 version. Silent Magician can negate a Spell Card per turn, so Fire King Island might end up being useless, so this is possibly one of the hardest matchups.
