The idea here is that every deck is trying to do something broken, whether it's cheating on mana, ritual acceleration, or winning with an empty library. The problem, of course, is that every deck is missing a vital piece to make it truly broken. For example, the Tinker deck has access to lots of early game low-cost artifacts as well as Tinker proper, but no one-hit K-O creatures like Blightsteel Colossus. Likewise, Storm has lots of ritual effects and proper Storm payoffs, but no filtering Cantrips or Yawgmoths will.
In place of the "missing pieces" are slightly less powerful versions of broken effects. Storm doesn't get Yawgmoth's Will, but it does get access to Magus of the Will and Gaea's Will. Tinker combo doesn't get Blightsteel Colossus, but it does get Ruin Grinder and Sharding Sphinx.
Because a key piece of every Combo deck is missing, they get a little help from other sources. For example, Storm gets help from amazing Magecraft cards like Witherbloom Apprentice to help deal any extra damage needed to win the game. Dredge can get help from the likes of Octavia, Living Thesis and Uro, Titan of Nature's Wrath to close out the game when Thassa's Oracle just can't.
However, a format where every deck is just a Combo deck would get old really quickly. Luckily, this deck has a few "fair" archetypes that enable for a more interesting metagame. In White, there is a Death and Taxes style strategy using Esper Sentinel and friends to draw lots of cards and flood the board with small things before the opponent has a chance to combo off. Blue-Black has a hand-disruption based control deck that uses Thoughtseize and friends in order to stop combos before they even start. Affinity, even though it tries to cheat on mana in its own right, works like a fair midrange deck in this Cube.
But even a "Combo and Disruptive Decks" Cube wouldn't necessarily have the most interesting draft experience. That's where this Cube's secret ingredient comes into play: some decks are using Combo cards to help with fair strategies! The Selesnya deck is a great example of this. Selesnya players create a wide board of White creatures and Green tokens, then use Leonin Lightscribe in addition to Manamorphose and storm cards to make a massive army all at once. There are all sorts of decks like this, such as the Haze of Rage+Dreadhorde Arcanist deck that pumps Dreadhorde Arcanist using Haze of Rage to create a massive storm count. Every combo in this Cube is unique!
