After its first release in the Structure Deck Legendary Warriors, the “X - Saber” archetype hasn’t received any further support in Duel Links until now; this archetype focuses heavily on the new summoning mechanic that has been introduced into the game so these additions were only to be expected.
X - Sabers have been associated with Hand Control in the TCG, but the Main Box Stardust Acceleration includes none of the cards that contributed to this fact; X - Sabers are well known for their ability swarm the field and Special Summon Synchro monsters with ease.
This deck is capable of summoning multiple monsters in a turn thanks to XX-Saber Boggart Knight, searching thanks Saber Slash and clearing the field and/or the opponent’s backrow for quick OTKs with Saber Slash and XX-Saber Hyunlei.
XX-Saber Fulhelmknight doesn’t have much going for him: he can negate an opponent’s attack once while it is face-up on the field, which is great, and, if you manage to destroy a monster in Defense Position with it, you get to Special Summon a Level 4 or lower “X - Saber” from your Graveyard, but the card doesn’t do much to make your Synchro Summoning plays easier.
Fulhelmknight is a Level 3 monster, which means that most of the times you will be able to Special Summon only Level 7 or 6 Synchros, unfortunately cutting X-Saber Wayne out of the deck.
Fulhelmknight and XX-Saber Boggart Knight or XX-Saber Garsem can make X-Saber Souza, whereas Fulhelmknight and XX-Saber Darksoul can make XX-Saber Hyunlei; if you use your Skill, you can also make Fulhelmknight Level 4, giving you access to Stardust Dragon
When Normal Summoned, this monster allows you to Special Summon a Level 4 or lower “X - Saber” from your hand—this is your way of swarming the field with this deck. Boggart Knight makes it easier to Synchro Summon and he also lets you abuse Saber Slash.
If Darksoul was sent from the field to the Graveyard, you get to add an “X - Saber” monster from your Deck to your hand during the End Phase of the same turn in which that happened, which means that its effect will trigger even if if you use it as Synchro Material.
An alternative to this card could really be any of the other two Level 4 “X - Saber” monsters from Legendary Warriors; Garsem is not necessary for the deck, but it can still reach a decent amount of ATK once there are two other monsters of the same archetype on your side of the field.
There aren’t really enough Synchro monsters to play around with, unless you are planning on using one of the “Mark of the Dragon” Skills, so Stardust is the only Level 8 you can add to your Extra Deck. Stardust Dragon is by no means game-breaking, but its effect can still be useful in certain scenarios; cards like Treacherous Trap Hole, Vampire Kingdom or even Donpa, Marksman Fur Hire and Recon, Scout Fur Hire can all be negated by this card and Stardust can just come back in the End Phase.
Your only way of Special Summoning Stardust Dragon is through your Skill: you Normal Summon Boggart Knight, Special Summon Fulhelmknight and then you change the Level of the latter to 4.
Hyunlei is very good against decks like Amazoness who rely strongly on their backrow. When Synchro Summoned, this monster allows you to destroy up to three Spell/Trap Cards on the field.
Hyunlei has only 2300 ATK, which is not much considering you are at least using two monsters to Special Summon it, but it mainly meant to be used to get rid or at least force the opponent’s backrow.
This is unfortunately the only monster you are going to be able to Special Summon most of the times. Souza’s effect can only be activated by tributing another “X - Saber” monster you control; most of the times you either won’t have something to tribute or you are simply not going to gain anything from it.
The first effect Souza can gain can essentially bypass Amazoness Onslaught, destroying a monster it battles with before the Damage Step—it could be interesting in combination with a card that lets you attack twice, but not nearly good enough to be actually used.
The second effect Souza can gain gives him immunity from Trap Cards that would destroy him like Treacherous Trap Hole and Widespread Ruin—it’s another interesting effect and possibly the most viable one out of the two, but, if your opponent knows about it, he is likely going to target him before you activate it.
Given how easy it is to get multiple “X - Saber” monsters on the field, this card is incredible: you get to destroy up to 3 cards on either side of the field and the effect doesn’t even target.
X- Saber will enable most of your OTKs with its effect; with some prior damage two “X - Saber” monsters are going to be enough to finish off the opponent.
One of the best cards you can keep in your deck for protection right now: Paleozoic Canadia can slow down many of the current top-tier decks and even prevent the opponent from performing a Synchro Summon. In addition to its first effect, Paleozoic Canadia can also be Special Summoned from the Graveyard as a Level 2 monster by chaining to another Trap Card.
Monsters used as Synchro Material end up in the Graveyard and this card allows you to get them back on the field with one additional Level and 100 ATK and DEF without being tied to it. Powerful Rebirth can sometimes allow you to Special Summon Stardust Dragon without having to use your Skill, which is great.
We are still looking around and wondering which Skill is the best for each deck, so this is just an early concept: Level Duplication lets you change the Level of a monster on the field with the one of another monster in your hand, making the Level 3 Tuner Fulhelmknight a Level 4 and giving you more options when it comes to Synchros.
One thing that we can’t ignore about these cards is that the majority are all Beast-Warrior and Warrior-Type monsters that can benefit from Sogen; Boggart Knight for example already has 1900 ATK and this card makes it reach 2100, which is nothing to laugh at for a Level 4 monster
Fur Hires are fast and consistent, something that can’t really be said for X - Sabers; Wiz, Sage Fur Hire can negate X - Saber Slash, which is pretty much your only way of getting rid of it if it’s in Defense Position, Donpa, Marksman Fur Hire can destroy your monsters and Dyna, Hero Fur Hire can banish them right afterwards. It’s not easy for anyone to face Fur Hires and now that Dyna is limited a lot of decks are running Wiz at three copies, which is not encouraging. In addition to not being comparable in terms of offensive power and effects, Fur Hires nearly don’t run backrow, which makes Hyunlei’s effect pretty much useless.
What can X - Sabers do to beat Fur Hires? Paleozoic Canadia is there for a reason, to slow them down and prevent them from getting Wiz out; without their 2800 DEF wall, clearing the board and causing heavy damage is not that difficult.
Amazons are a bit of a slower deck, they mainly use their backrow to keep control of the field and Amazoness Princess for consistency. Paleozoic Canadia can limit the use of Saber Slash and Amazoness Onslaught can banish your monsters, including the ones from the Extra Deck that you put so much effort into summoning, but at the same time Hyunlei can get rid of all of these card that could stop the deck, Souza can even attack Amazoness Queen and destroy it with its first effect and Saber Slash is still a pretty big threat as, without their backrow Amazons don’t have much going for them.
The winners of the KC Cup are not an easy deck to deal with, but the fact that they tend to reduce their Life Points pretty drastically so early may be enough of an opening to end games quickly. The only cards that may cause problems in this matchup are Treacherous Trap Hole and Simultaneous Loss + Vampire Kingdom as they are the main forms of removal that can be used during the opponent’s turn.
Most Vampire decks only run 1 or 2 copies of their Field Spell and, if you get rid of it, searching it again may cause some trouble for a player that is already at 2500 Life Points or below after their first turn.
Masked HEROes are fast and can usually end the game in a couple turns if the opponent’s deck just can’t keep up. Your best way of dealing with this deck is to slow it down with Canadia and then go on the offensive once the opponent has expended most of its resources.
Paleozoic Canadia is once again crucial in this matchup as it can prevent the opponent from switching U.A. Midfielder out or even from activating its effect if you target the monster he targeted.
One of the biggest threat for this deck are Spellbooks in combination with Silent Magician. Silent Magician can prevent you from activating X - Saber Slash, Silent Magician LV8 is immune to it and, once it touches the field, your best way of destroying it is with either Souza or after flipping it with Paleozoic Canadia and all of this is before even taking into consideration the constant threat that is Spellbook of Fate.
