Let me present to you Chrome Box, a variant of battle-box/cubelet Magic with a couple twisted rules.

Chrome Box can be started with near to zero setup and closed without having to separate the lands from the rest. Rules are as follows :

• One big shared library.
• Shared graveyard. "Your graveyard", "An opponent's graveyard" and "All graveyards" are the same thing.
• No basic lands. You can play any card from your hand as if it were a basic land by playing it flipped (upside down). From that moment, the card is a basic land which can produce mana of any of the colors of the mana cost printed on it and it has all corresponding basic land types until it leaves the battlefield. (it means that it's possible to blink a flipland and have it return as the card it really is). [Chrome Mox] almost does that, hence the format name.
• When a player searches the library for a card, that player can only take one handful of cards from the top of the library, which is the limit for how deep they can search and shuffle the library. Same goes for putting cards at the bottom of the library, you put them under the top biggest stack of cards you can pick with one hand (this rule exists to counter the tendency to always search for the same cards, and it also saves a lot of time).
• The first player to play a card starts the first turn of the game (it takes time to figure out all 7 cards you've been dealt, and which one you're going to play as land first, so the first player who comes up with a decision can start; in this format who's starting is not significant).

Chrome Box is fun because the shared graveyard and library and the land rule give rise to some twisted mechanics in cards you wouldn't think of at first. Playing expensive stuff as lands to hide them in plain sight, then sacrificing them (or destroying your opponent's) to reanimate them.

I've never met someone who had already played it that way. It sure is fun though, and some Cubes can surely make it work without removing cards from them.

This list has been played and curated for a year and has recently (May, 2024) undergone a harsh cutdown from 900+ cards to 350 cards. It's now very clean and has good potential. Expect a change in the following couple of weeks, as the current list state probably still needs some balancing between permanents and spells, especially under the board management angle.
