penguin soldier is a funny side deck card against gladiator beasts but i do not see why you would main or side it this format; it seems like it's been a long time since glads topped anything
triple fautroll actually can work and is awesome, but the only builds i've seen do it are ones that also maxed out on Duality and Gottom's Emergency Call (which by the way I also recommend)
i will freely admit that i do not have much experience piloting x-sabers myself, but i know a lot of people irl who do and based on their builds, and playing both with and against sabers, i would recommend:
-1 swords of revealing light
-1 card trooper
-1 xx-saber fulhelmknight
-2 reinforce truth
-2 compulsory evacuation device
-2 penguin soldier
-2 x-saber airbellum
-3 saber hole in main deck
-3 saber slash
-1 red dragon archfiend in extra
-1 x-saber wayne in extra
-1 scrap archfiend in extra
+1 heavy storm
+1 reinforcement of the army
+1 pot of duality
+1 monster reborn
+1 book of moon
+1 forbidden lance
+1 solemn warning
+1 trap stun
+1 torrential tribute
+1 super-nimble mega hamster
+1 xx-saber darksoul
+2 mystical space typhoon
+2 call of the haunted
+2 effect veiler
+1 x-saber urbellum in extra (rarely a good choice tbh, but it's at least on-theme unlike scrap archfiend meaning boggart knight can be used to make it in a pinch)
+1 naturia beast in extra
+1 of the new x-saber xyz in extra (honestly have not gotten a chance to try him out yet
and wouldn't be surprised if that makes this entire post outdated info)
+2 saber hole in side deck
+2 trap stun in side deck
+1 mst in side deck
side decks should really be the kind of thing the player decided for themselves but i see these as a must tbh
i really hate telling people to take out 10+ cards of their deck, doubly so when talking about irl builds, but in this case i feel it's highly warranted lol
now what i will admit is a few points of contention with other saber pilots:
1) whether reinforce truth is worth running at all, and if so at how many copies; personally i don't like the card at all and think it just takes away space you could be using on better cards
2) how many effect veilers to run, if any: i like two, many people i know say 1 or even 0, but i get the feeling a lot of those people are gonna change their minds on this once inzectors are legal in the tcg
3) double call of the haunted: i like this in x-sabers because it makes gottom's emergency call live more often, plain and simple. you can easily go from having 0 monsters on field to 3 by reviving a mon with call, then flipping emergency call to get out two more
4) mst vs trap stun; i like maining 2 mst and 1 trap stun, going into the sideboard game 2 and swapping depending on the match-up
