  • Fire King Courtier Ulcanix
  • Any FIRE monster
• In main deck:
  • Legendary Fire King Ponix
  • Sacred Fire King Garunix
  • Fire King High Avatar Garunix
  • Fire King Avatar Arvata

• In the Extra Deck:
  • Salamangreat Sunlight Wolf
  • Promethean Princess, Bestower of Flames
  • Amphibious Swarmship Amblowhale
  • For Route 1, I:P Masquerena (and a valid card to Link her into, like S:P Little Knight, or Knightmare Unicorn), or a Link-2 of your choice.
  • For Route 2, Relinquished Anima

When to perform this combo

Whenever you have Ulcanix and a FIRE monster in hand (even if it's Ponix).

If you have Arvata, you are protected from Nibiru provided you don't meet other interruptions.

Steps:

• Normal Summon Fire King Courtier Ulcanix.
• Activate Ulcanix's effect, destroying the FIRE monster in your hand to search Legendary Fire King Ponix.
• Activate Ponix's first effect, to Special Summon itself from the hand.
• Activate Ponix's second effect, to add Fire King Sanctuary from deck to hand.
• Activate Sanctuary, place Fire King Island in the Field Zone.
• Activate Island, destroying Ulcanix for Sacred Fire King Garunix.
• A chain forms with Sacred Garunix and Ulcanix:
  • Ulcanix Special Summons Fire King High Avatar Garunix from deck.
  • Sacred Garunix Special Summons itself from hand.
• Activate Sacred Garunix's second effect to destroy Fire King Avatar Arvata from deck.
  • If the FIRE monster you destroyed with Ulcanix was Arvata, destroy Fire King High Avatar Kirin instead.

Route 1 - sets up a Link-2 in GY to revive with Amblowhale

1. Activate Arvata/High Kirin after being destroyed by Sacred Garunix, to Special Summon Ulcanix from GY.
2. Link Summon Salamangreat Sunlight Wolf using any 2 monsters.
3. Link Summon a Link-2 of your choice (for example I:P Masquerena or Duelittle Chimera) under Sunlight Wolf, using the other two monsters.
4. Sunlight Wolf effect to add a FIRE monster from GY to hand.
5. Link Summon Promethean Princess, Bestower of Flames using Sunlight Wolf and the Link-2.
6. Activate Princess effect to Special Summon a FIRE from GY.
7. Link Summon Amphibious Swarmship Amblowhale using Princess and the FIRE monster.

Route 2 - trades the Link-2 in GY for a negate with Arvata

1. Activate Arvata/High Kirin after being destroyed by Sacred Garunix, to Special Summon Ulcanix from GY.
2. Link Summon Salamangreat Sunlight Wolf using any 2 monsters, except Ponix.
3. Link Summon Relinquished Anima using Ponix, in the zone under Sunlight Wolf.
4. Sunlight Wolf effect to add a FIRE monster from GY to hand, except Arvata.
5. Link Summon Promethean Princess, Bestower of Flames using Sunlight Wolf and Anima.
6. Activate Princess effect to Special Summon Arvata from GY.
7. (Optionally) Link Summon Amphibious Swarmship Amblowhale using Princess and the remaining monster besides Arvata.

Route 2, extended - if Arvata was the FIRE monster; can play into Nibiru and negate it

1. Activate High Kirin after being destroyed by Sacred Garunix, to Special Summon Arvata from GY. This is the 5th summon, so Nibiru is now online.
2. If Nibiru is activated, negate with Arvata and destroy Sacred Garunix.
3. Resume Route 2 by Link Summoning Salamangreat Sunlight Wolf with High Garunix and Arvata, and continuing with Step 3.

Notes

You should have most of the interruptions from the 1.5-card Ponix combo. If all goes well you will also have an additional Link-2 or an Arvata alongside them.

If you chose to Link Summon I:P Masquerena, you will need to sequence your interruptions differently. Ideally, you returned a Kirin to hand with Sunlight Wolf, so you can use it to pop Amblowhale instead of popping it with Princess. Otherwise, you cannot revive Masquerena using Amblowhale's effect while Promethean Princess is on the field, because she locks you into FIRE monsters only.

Chokepoints

• The same issues from the previous two combos apply to this one. Ulcanix, Ponix and Island can be easily negated and will stop your combo.
• If Sacred Garunix is negated on the field, you have 3 monsters on the field, so you can make Sunlight Wolf and Anima, then Link into Princess. You just won't be able to get Arvata on the field.
• If Sunlight Wolf is destroyed before you can summon the other Link monster, you are left with 2 monsters on the field and little way to progress. If your opponent has a FIRE monster in their GY, look to summon Hiita the Fire Charmer, Ablaze and steal it, so you can make Princess and Amblowhale.
