Here's my sample list. It borrows some elements from HunterSerge's build, but with my personal twist aided by Miracle Impack. Every card choice will be briefly explained.

BUDDY: Demongodol Ark

MONSTERS: 24

Demongodol Ark x4 - And he's my buddy too? Yep. Because people forget that Ultimate Buddy exists, and it's a good card to run at 1-2 copies in this deck...as a sideboard card.

Rahal x4 - Maddog is spot-on with this one. So what if it's a Size 2? You need Rahal on turns that you don't have Ark in your opening hand. Anything that helps you stay alive longer FOR FREE always helps, even with Kibaltes around. In fact, having both Rahal and Kibaltes keeps you healthy a lot better than life gain tricks from Beast Aura variants.

Kibaltes x4 - Because reasons. See Rahal.

Foonbaltes x4 - Reach will never be a problem with what I consider the best vanilla in the game at this time. That 6000 attack will threaten most Size 1s, a whole lot of Size 2s, and even a couple of Size 3s.

Medrogiras x4 - Six copies of Ultimate Buddy, four of which are Duel Dragons that Ark can evolve from, is always a nice thing to have. That 2 crit also helps. Remember to expend him for Soulguard first before anything else so you can recycle him with Unyielding Spirit.

Valken/Zald x2-4 - Okay, I did say Beast Aura was bad, but Valken has all around-stats that make it hard to ignore. I'd rather run this than a costless 3-crit vanilla because that extra damage won't do anything if you can't break the center open. This gives you exactly eight monsters that can link with Ark to breach 12,000 defense (Tempest Enforcer). Actually, I just like having enough monsters that can link for good numbers, period. Just consider the ability a bonus for emergency situations. Also...Valken's ability increases the chances of getting targets in the drop for Unyielding Spirit, as well as keep you healthy enough to use a certain spell that needs life payment. You can easily replace two copies of this with Raging Dragon, Zald if you want.

ITEMS: 6

Ricdeau Demon Slay x4 - This needs no explanation.

Dangerous Cradle x2 - THIS needs some explanation. Space in Demongodol Ark decks is a valuable commodity. I'd rather have 2 extra defensive spells or a quality impact than clogging my hand with weapons.

SPELLS: 20

Demon Slay Barrier x4 - Standard for this deck.

Battle Spirit Infusion x4 - Pretty standard for this deck.

Battle Aura Circle x4 - As standard as standard gets in Danger World.

Dimensional Demon Slay Slash x2 - Works better than Lord Aura Meditation, trust me. This screws with Dungeon World so much, it's not even funny. That one gauge they need for Divine Protection of Shalsana just bit the dust.

Unyielding Spirit x4 - The spell Duel Dragons have been waiting for! This allows you to recycle your Movers and Medrogiras after it has been spent for Soulguard. Finally, you have plenty of ways to get Demongodol Ark into your hand. You have Ark too early, charge it. Once you equip the Axe, Cradle's ability, or even activate Beast Aura (last resort), Ark's right there for the taking

Battle Dragon Slaying Crush x2 - Because Stars is a thing, as well as the many life-saving items and set spells out there. Get your monsters online again by crushing Great Fate Frozen Stars, guarantee the finish by smashing Glory Seeker / Dragon Return System / Crush that Body to Sustain Mine, or even a center blocker/mover. So many uses for this card, but the 2 life cost is too steep for you, just drop this in favor of Demon Slay Resurrection.

ALTERNATIVE STRATEGIES:

You can rush your opponent if you want until Ark shows up to slow the game down again. If that's your preferred gameplan, just drop Dimensional demon Slay Slash and Battle Dragon Slaying Crush in favor of life gain such as Demon Slay Resurrection and move them to the sideboard, then replace a few copies of Kinbaltes/Valken with Zald.
