update 13/01/2018


The main box Primal Burst brought a lot of Archetypes with it (Dark World, Volcanics, Cloudians, Gem-Knights), and to many people’s surprise it is actually possible to build a semi-competitive Gem-Knights deck right now in Duel Links.
The reason this fusion-based deck actually works is because of all the possible combinations to fusion summon and the cycling power that is possible with it thanks to Fusion Recycling Plant, Volcanic Shell, Gem-Knight Lazuli and Thunder Dragon.

Set skill

[Skill] descriptionUser
Can be used after starting hand is distributed. Shuffle all the cards from your hand into the Deck. Then draw the starting hand again.

How to use this deck

Fusion Recycling Plant

This is the card that makes the deck work. Preferably you would have 3 copies of this card and run it with only 1 copy of Polymerization. Its first effect lets you discard one card to add a Polymerization from your deck OR graveyard to your hand. This is why you only need 1 copy of Polymerization.Its second effect gives you back a monster from your graveyard that was used as a fusion material this turn.

  • A nice combo with this card is to discard a Volcanic Shell to add a Polymerization to your hand, and then use the effect of Volcanic Shell to add another Volcanic Shell to your hand.

Gem-Knight Lazuli

The strength of this card comes from the fact that when this card is used as a fusion material, you can add 1 Normal monster from your graveyard to your hand. So say for example you fusion summon a Gem-Knight Citrine by using Gem-Knight Garnet + Gem-Knight Lazuli , you immediately can add back that Gem-Knight Garnet to your hand, and at the end of your turn you can add back Gem-Knight Lazuli through the effect of Fusion Recycling Plant. Next turn you can discard a card (preferably Volcanic Shell) to get back your Polymerization at which point you can fusion summon again because you got back all your materials.

  • Keep in mind: discarding Gem-Knight Lazuli to add a Polymerization to your hand with Fusion Recycling Plant will not activate Lazuli’s effect to add a Normal monster from your graveyard to your hand.

Gem-Knight Garnet & Gem-Knight Tourmaline

The ratio you’d want to run in your deck depends a bit on what you want or prefer. We included 2 copies of each in the example deck to give a general idea, but if you feel you want to get Gem-Knight Citrine more you might want to run 3 copies of Gem-Knight Garnet.
They both are Normal monsters so they can be added to your hand through the effect of Gem-Knight Lazuli and they both have a different type (Thunder and Pyro). Always think carefully about what fusion monsters you want/can summon. For example if you have both Gem-Knight Garnet and Gem-Knight Tourmaline in your hand you can fusion summon ANY of the four fusion monsters included in this example deck.

Non Gem-Knight supports

  • Volcanic Shell: Besides being a Pyro monster, meaning it can be used in combination with Gem-Knights to fusion summon Gem-Knight Citrine, the reason this card is so important in this deck is because you can pay 500 life points when this card is in your graveyard, to add another copy to your hand. So it’s an important card to go +0 or +1 when fusion summoning (instead of going -2).
  • Thunder Dragon: The effect essentially gives you a +1 while also thinning your deck. This is great because it means that you could discard one of those two Thunder Dragons for the effect of Fusion Recycling Plant, and besides that, they are also Thunder monsters so they can be used to fusion summon Gem-Knight Prismaura.

Supports spells/traps

  • Super Rush Headlong: Very effective card to destroy your opponent's monster. Don’t forget if you attack and your opponent tries to defend with a Super Rush Headlong, you can chain yours to it and because you are the “turn player” you will have priority and your monster will survive while his will be destroyed.
  • Windstorm of Etaqua & Curse of Anubis: They are both great to defend your monsters, stall a bit, and allow you to go more offensive on the next turn because you won’t have to fear Wall of Disruption and Mirror Wall as much as when your opponent’s monsters are in attack position.


  • Citrine: This is the fusion monster you’ll want to summon most of the time because of its effect. Your opponent can’t activate any spells/traps when this monster attacks or is attacked, which adds a nice layer of defense to it.
  • Prismaura: This card has a powerful effect that lets you send one Gem-Knight from your hand to your graveyard to destroy one face-up card on the field, so it’s a great way of dealing with strong monster or troublesome spells/traps (for example Temple of the Mind's Eyee).
  • Ruby & Topaz: Although you’ll probably summon these monsters the least amount of times, they both have an interesting effect that could be game-winning in certain situations. If you find yourself never using them, you can add another copy of Gem-Knight Prismaura Gem-Knight Master Diamond.

Other useful cards

Wall of Disruption
Wall of Disruption
Still a great defensive and stall card, although it has lost a lot of popularity recently because of Sergeant Electro being so good right now in the Meta.
Mirror Wall
Mirror Wall
Because Wall of Disruption can’t be chained to the effect of Sergeant Electro, and Wall of Disruption is almost useless against Ancient Gears, some people prefer to use Mirror Wall to defend themselves.
Planet Pathfinder
Planet Pathfinder
Used to get Fusion Recycling Plant more consistently, and can be used as fodder for it to discard.
If one of your fusion monsters would be destroyed, you can use this equip spell to bring them back in exchange for 800 life points. Although this card could be very bricky at the start of duel, you could possibly get a lot of value out of it later on in the duel.


Hot New Top

I've been having fun testing out the gem knights in duel world, but is there anything else that might help this out or that I should include more of? Extra deck is: 1 Prismaura, 2 Ruby, 1 Topaz, 1 Citrine. (I use Fusion gate because I don't have fusion recycling plant yet).

It's a bad trap card... It's like a Mirror Wall that only works during the summon, I'd replace it with a Windstorm instead.

I admit that I love it for Ancient Gears, but Etaqua stops more at once, so I'll switch to that. Thanks!

Seriously bud don't go for the gameA deck it truly undermines the real strength of this deck. Get one particle fusion for sure . It is superb option to dish out pain against very heavy hitters

Since I do have paricle fusion, I'll try using it. I was mainly worried about using Fusion Time!, but it should be alright to have both. I also took out Topaz for another Citrine and swapped out Adhesion Trap Hole for Etaqua.

I'm confused, I SHOULDN'T use Particle Fusion and three Rubies? Why the hell not? I can amp up ruby to insane ATK strength using these cards, even more so with Master Diamond! And here I thought the only thing holding me back against tougher opponents was a lack of decent staples...

I truly disagree with the review . And I think this deck can reach to top in good hands.

My deck
2 garnet , 2 sardonyx , 2 kuriboh, 1 thunder type GK , 1 lazuli ,

It's power drawer sardonyx can bring the much needed cards for fusion and having fusion time! Clubbed in this deck is just too good for synergy. If you want a heavy hitter you have garnet . Still u wanna match a BEWD Or any super powerful monster fuse using particle fusion and dish out pain.
And if you want an element of surprise set pyroxene fusion and shock them. If u want to end the match just get particle fusion and end the duel right away.

Every card in this deck is my favorite but the ones I d like to point out are:
Ruby : fuse up using particle fusion and most of the duel end in turn 3 or 4 , thanks to its piercing battle damage .( Use it only when you are sure they don't have card in their back row which could cause problem)
Garnet : if your opponent has full back row then this card is your prime choice .
Seraphinite : best for swarming the field as it allows an extra special summon.

U can have half of this deck on only 3 to 4 purchases with gems.

Nah this deck isn’t good. Emerald and sardonyx are useless most of the time outside of being 1800 beatsticks. And prismatic fusion is pretty hard to get off because there’s a lot of fast decks and strong backrow
