This is adapted from Andy mangold's Bun Magic cube..
The Bun Magic Cube is a vintage, unpowered cube designed to push Magic's core strategies — aggro, midrange, and control — to their limits.

I am seeking to replicate its low curve, mana fixing, interaction of all kinds, modal and otherwise flexible cards, and symmetrical effects.

I run booster tutor in all my cubes as the most fun cube card. Other than that, I do not use any un cards.

I also have chosen not to use any fast mana or ramp cards outside of green. I also do not support combos.

Power

Copied from Andy-
I aim to optimize my cube for power and consistency within the scope of what I deem to be 'fair' strategies. I exclude individual cards which offer their caster an outsized advantage with minimal or no deckbuilding cost (The Power Nine, top-tier fast mana like Sol Ring and Mana Crypt, Mind Twist, Mana Drain, etc.), strategies that are linear and largely non-interactive (combo and storm), and cards that cheat mana costs (Tinker, Natural Order, reanimator, etc.). My goal is to push the core strategies of the game — aggro, midrange, and control — to their most powerful limits while still remaining in balance with one another.

Gameplay

I want to enable my players to express their skill and empower them to control their fate through their draft, deckbuilding, and gameplay decisions. While I believe variance is an inherent and essential part of the game, I want to offer my players the opportunity to minimize that variance with an abundance of mana fixing, modal cards, and efficient card selection. My ideal games are relatively fast, with the deciding plays happening before turn five, and narrow wins that are one decision or card away from the opposite outcome. I accept the occasional non-games and swingy plays as a byproduct of the power-level at which I choose to play, but only if those non-games are the result of conscious deckbuilding and gameplay decisions, like the successful execution of an Upheaval deck, rather than on the back of singular, powerful cards, like Mind Twisting away your opponents hand. I am especially interested in 'symmetrical' effects that can be abused with selective deckbuilding.

Adaptions

Since copying the initial list in Jan 2022, I have begun to adept it for my preferences and my cards. I have exchange one set of shocks for duals and 1 for a combination of bicycles, triomes and other lands that make sense.

Starting with kamigawa I will be adding cards independent of the original.
