Any of these will work, but I'll show you what my Dark World deck looked like at this point in time: Monsters(20): 2x Beiige, Vanguard of Dark World 3x Broww, Huntsman of Dark World 3x Cyber Dragon 2x Fabled Raven 3x Goldd, Wu-Lord of Dark World 1x Morphing Jar 1x Sangan 3x Sillva, Warlord of Dark World 2x X-Saber Airbellum Spells(12): 1x Dark Hole 3x Dark World Dealings 3x Dark World Lightning 2x Gateway to Dark World 1x Monster Reborn 2x Mystical Space Typhoon Traps(8): 3x Dust Tornado 1x Mirror Force 1x Solemn Judgment 1x The Forces of Darkness 1x Torrential Tribute Extra(15): 1x Ally of Justice Catastor 1x Ally of Justice Field Marshall 2x Ally of Justice Light Gazer 1x Brionac, Dragon of the Ice Barrier 2x Dark End Dragon 1x Flamvell Uruquizas 1x Goyo Guardian 1x Lightning Warrior 1x Magical Android 1x Mist Wurm 1x Naturia Beast 2x X-Saber Urbellum Back in story mode, it's time to challenge Klaus
The idea is to start with A2-111, attach a Tool, and deal 50 damage right away, giving the deck early aggression
Theres a ton of overlap in ways to make all of the aspects of historic apply in Cube, and K-9, Mark I stands out to me as being very useful specifically in this space

Often Valduk ends up just being a legendary 3/2, awkward if you took this over removal or some solid all-around card
Elemental Bond + Tribute to the World Tree Elemental Bond versus Garruk's Uprising sparks an interesting discussion, but I favor Elemental Bond as it has a lower threshold for that juicy card draw
