Order Beast Warrior (KP10 Build 1 Prerelease)
KP10 Requiem of Destruction introduces some support cards to the ailing Beast Warrior type, providing some decently potent tools.
This serves as more of a draft, and while I haven't played with all of the available support cards (Beast Gear Sage Roller Stag for example), at worst this build is a standalone build of the deck, though I might post a list using the other support cards if and when I get around to testing it.
For now, this is a simple Beatdown strategy utilising Heartless Hound Martial Master Shiba, which can revive any Level 5-7 Beast Warrior from your grave. Notably, this doesn't incentivise you to play low level Beast Warriors, which gives us the opportunity to sift through the pile of generic utility monsters. What is important is the higher level Beast Warriors we choose to run. I've opted for Savage Claw Tiger as the premier beatstick that you aim to special off Shiba. Getting Tiger off Shiba lets Tiger be at at least 3.1k ATK, which is a sizeable number. The reason why the deck is not on the other in-theme boss monster, Heartless Hound Thunder Emperor Drainu, is because it doesn't help hit good numbers. Assuming you don't have Apocalypse - Beast Gear World on field, if you're staring down 2 2.5k attackers (e.g. 2 Galactica Oblivions), specialling Drainu doesn't help you beat over any of them, at best you crash into one of them with Shiba. By summoning Tiger, you will be able to beat over 1 of them. Not having Drainu's special summon effect clog the board means that we can more easily activate Secret Order to special summon Heartless Hound Apex Katana Danbiramatian and get 3 decently sized beatsticks onto the board. With 3 Level 7-8s on board Tiger will now be at 3.5k ATK. While Ultimate Flag Mech Tough Striker is a bigger Secret Order target that also gets buffed by Beast Gear World, Danbiramatian being an actual Beast Warrior lets you special it off of Shiba if you have no other option. While I haven't tried Roller Stag yet, its low stats make me apprehensive about its viability, and while it is able to recycle Beast Gear Secret Art - Primal Fist, that's provided you have a copy in rotation in the first place. That being said, the potential upside is still quite alluring so I'll have to test it out myself. For now, this streamlined beatdown build is capable enough.
As for the low levels, 3 Sea Dragon Knight and 1 Siesta Torero are here partly as ways to shuffle Shiba back into deck. While you have many ways to recur Savage Claw Tiger and Danbiramatian, Shiba, being a Level 8, is harder to access. Being able to shuffle it into deck to then hard draw back into it to reset your board is a good ability to have. Sea Dragon Knight helps check backrow, extremely helpful especially with the only way to play around backrow other that Sea Dragon Knight is Secret Order, and it's not infallible. 1 Siesta Torero, alongside 3 Sevens Road Mage, are here to help beat over other monsters. While Savage Claw Tiger can do that on its own, Shiba can't, and having ways to help Shiba do exactly that is nice to have. This also helps Danbiramatian when you can't Secret Order it out. We've chosen Mage specifically over something like Fortitude Dragon on the off chance you need to use 2 of them on something like a Cosmo Titan or you need to debuff an ATK position Shock Dragon and the stat difference shouldn't matter enough, but this choice is largely negligible. 3 The Strange Specter of Celestial Severance and 3 Amazing Dealer are part of the consistency tools in the deck, Amazing draws deeper into the deck and Specter sifts through the top 3 of your deck to set up your grave, which is very handy for early game Shibas. Rhythmical Performer is also a part of this, but is more luck reliant. We've chosen is over a similar card, Upstart King Rex, firstly because against a popular deck like Gate Order the odds of it drawing a card are higher, secondly because the mill 1 sets the grave up ever so slightly, and thirdly as you can use multiple of them in a single turn. With the introduction of Trap Lid, Gate Order will likely dip in popularity however, so I might end up swapping to Upstart King Rex once the set is fully revealed and the meta settles down. Beast Summoner, while unable to summon Shiba, is able to cheat out a Tiger or Danbiramatian in hand, which allows it to dodge something like Crisis at the Sacred Tower, or in general alongside Secret Order just more effeciently be able to make boards.
Now for the spells. 3 Secret Order as a very strong card for providing tempo among other reasons. 3 Ship of Seven Treasures as a consistency tool alongside the 6 Level 7s in the deck. 3 Apocalypse - Beast Gear World helps your monsters win combat both on your turn and your opponent's, very handy for establishing control of the board. It also enables the 1 of copy of Apocalypse - The Unstoppable Beast-Warrior, which I'm a fair bit iffy on at the moment since it requires having the Field Spell on board which isn't guranteed, but if you do get to activate it it's able to special summon Shiba, one of the few ways to fetch it out, and provides a source of piercing, which helps end games faster. Magical Stone Excavation as a 1 of acts as a "wild card", being able to be replaced by any spell in your grave by discarding 2 cards, allowing you to recycle Secret Orders and Unstoppable Beast-Warriors, or even the field spell. Lastly, Mirror Force as the legend of choice as a strong power one-of. Helps retain tempo or is a strong comeback tool.
Overall, the build is extremely simple. Make multiple beatsticks, swing with multiple beatsticks, rinse repeat. Roller Stag can give a bit more spice to the strategy, but I haven't tested it yet myself to make any more comments on it than I already have. Ideally I'd want Beast Warriors to have a good incentive to run their low levels, but for now I'm fine with how the deck's turned out. A farcry from the low-power Beast Warrior strategy before KP10 in terms of viability, which is a huge step-up. If you're looking for a simple "turn-brain-off" deck to play, this deck is for you.
