This cube is called Cubiquitious because it is always on my mind, everywhere I go... and it's a cube. It is meant to bring what I would call a Modern+ flavour, with (formerly?) popular cards from the format like Bolt, Urza, Omnath, Karn Liberated, DRC, fetches, shocks and triomes, plus sideboard-specific cards to give it that constructed feel, as well as broken stuff you can't do in Modern like Tinker, Oath, Channel, Balance, Sneak, Fury and Grief. It's also meant for you to be able to go 3-4 colours fairly easily, and as such each archetype is supported across that many colours - so mixing and matching your archetypes is pretty easy too.

Artifact Soup -

• You ever Tinker or Goblin Welder for a Bolas's Citadel? I have, it felt great!
• Sai, Master Thopterist, Saheeli, Sublime Artificer and Time Sieve would like for you to pack your deck with artifacts

Flicker -

• Kiki, Pestermite, Splinter Twin, Deceiver Exarch, Zealous Conscripts, Village Bell-Ringer and Restoration Angel are all here to annoy your opponents
• When you aren't trying to win the game on the spot, Ephemerate, Soulherder and Abuelo, Ancestral Echo your Fury, Mulldrifter, Knight Of Autumn and Wall Of Roots for all the value you can handle

Aristocrats / Sacrifice -

• The above, Cruel Celebrant, Zulaport Cutthroat and Corpse Knight invite you to play all the creatures
• Pia And Kiran Nalaar, Makeshift Munitions and Bontu The Glorified let you throw your stuff at things

Ramp / Reanimate -

• You ever cast Primeval Titan or Cultivator Colossus with a Tireless Tracker and/or Tireless Provisioner on the battlefield? It's neater than a potato
• Go ahead and Persist that Archon Of Cruelty… or Channel that Ulamog, The Ceaseless Hunger… or Trash For Treasure that Sundering Titan

Classic Midrange -

• Just like The Acclaimed, everybody loves Ravenous Chupacabra and Gonti, Lord Of Luxury
• Tick up/down your best girls Chandra, Torch Of Defiance, Kaya, Orzhov Usurper, Nahiri, The Harbinger… and Grist, The Hunger Tide who is indeed a girl!

Colourless Cards That Go In Numerous Decks

• Omnath, Locus Of Creation is a good pal for Golos, as is Sylvan Scrying for more FOTD tutoring
• How about Zuran Orb, Titania, Protector Of Argoth and Sylvan Safekeeper to hang out with your Field?

• 10/10 Proper Fetches
• 10/10 Shocks
