  • This card can replace 1 Fusion Material Monster.
  • It can Special Summon a Fusion Monster from your Extra Deck.
  • Defense is pretty decent.


  • Attack is quite low which makes it unreliable in battle.
  • Even though the Defense is decent, there are still a lot of monsters that can surpass it.
  • The other monster to be used in Polymerization with this card should be the correct monster.
  • You must tribute this card and a Fusion Material Monster from the field in order to Special Summon from your Extra deck by its effect.
  • It can only Special Summon a DARK Fusion Monster from your Extra Deck by its effect.


Monsters to summon

  • B. Skull Dragon currently has the highest attack out of all DARK Fusion Monsters. Use The Dark - Hex-Sealed Fusion's effect to tribute it and one of the Fusion Material monster from the field.

I can't special summon Red Eyes Slash Dragon even when I have this card and Red Eyes B. Dragon on the field. What am I doing wrong?

This card can be used as a substitute for red eyes b. dragon, but not for a generic warrior monster. The thing you're doing wrong is trying to fuse 2 re-eyes b. dragon together. You need a warrior on the field to make it work.

That makes a lot more sense now. Thank you!
So when you first summon it to the field, do you need polymerization if you have the other correct monsters, like just machine types affected by dna transplant (tryna summon chimeratech)

I don't know... As someone who uses the Light version of this card when I had Sparkman in the field to try to summon Shining Flare Wingman it didn't let me tribute to summon it.

The Hex-Sealeds have two effects. You can use them as a regular fusion substitute with Polymerization (like you would Versago). Or you can Tribute them and the other materials for a Fusion from your field to Special Summon the Fusion.

Keep in mind that second effect is NOT a Fusion Summon, though. So you can't Summon something like Shining Flare Wingman that has to be Fusion Summoned.
I couldn't FUSION-SUMMON (w/ polymerization) Buster Blader the destruction swordmaster usind this card and an Explosive Dragon in my hand as Fusion Material... anyone knows why? :'(

It does not matter what attribute if he uses polymerization.

Are you trying to summon the BBdragon swordmaster? Of course you cannot, because the BBswordmaster is NOT treated as Buster Blader in hand, BUT you can use that dark he + BBswordmaster to Red-Eyes Slash Dragon

That's because BB Fusion is a LIGHT monster. It would only let you summon Dark Paladin in that case. Read that card attribute before complaining.

...The Dark - Hex-Sealed Fusion has two effects. He was talking about just using it as a regular fusion Substitute with Polymerization. The Attribute of the Fusion is irrelevant for that effect.

Unless this was a Vagabond game with no Special Summons, he forgot to add the Swordmaster to the Extra Deck or the opponent had something blocking Special Summons, what he said should have worked.
Red-Eyes Slash Dragon!!!

So it says a fusion monster namely any plus light hex sealed fusion may summon a blue eyes ultimate dragon or whatever, it appears that way.

"All other materials must be Corect" this is a one per kind of deal friend.
easy to get and great in buster blader deck.
Would this work on monsters in the extra deck that don't use POLY. Like GB or NEOS monsters?

No, they (at least the more recent ones like Nerokius) pretty clearly say they first have to be Summoned with the listed method. (And since it's not a Fusion Summon, you can't use them as regular Fusion Subs for these Summons, either.)
So, I get that when it's on the field with another 'correct' card you can fusion without poly. Can you however use it WITH poly from your hand as a sub for fusions vs the "on the field" requirement?

If you're using POLY then it does not matter where any of the fusion material is (both in hand, on field, or one and one) they all work
This can be used to summon Red Eyes Slash if you have warrior.

After special summon and sent to the graveyard it can't be brought back with spirit nor wyvern, is that a bug?

No, it's not. You didn't Fusion Summon it, so you can't SS it from GY after it was sent there.
People need to realize that Dark Paladin MUST be fusion summoned. Read the card guys.
Doesn’t work for paladin I lost a pvp duel cuz of it
That artwork is so disturbing
