This Cube is made with the best our Playgroup can muster.
Only Sol Ring got left out of this cube due to sheer overpoweredness, otherwise this is as amped up as we can go.

And as a little bonus, Combo: this cube is a little less fair than we are used to (and also we don't have all of the combo pieces), so I kept Combo at a minimum. Putting together a Storm or Splinter Twin Deck is more of an achievement rather than the norm. But it certainly is possible - there's also Persistent Combos and Vizier of Remedies has Devoted Druid as well.

For Splinter Twin there's only Kiki-Jiki, not Splinter Twin and no Recruiter of the Guards, but there are 3 Kiki targets in Restoration Angel, Zealous Conscripts and Pestermite.

Storm has Tendrils of Agony, Empty the Warrens and Mind's Desire, but not many wheels or Yawgmoth's Will. There are Rituals and Mana Doublers, so getting as much efficient card draw as possible is crucial. Windfall, Commit//Memory and Wheel of Fortune are the only Wheels present.
