I have a friend who created a format similar to Battle Box about 7 years ago.
I shall now introduce you to
Enigma Duel
Setup
It is like a cube (or a giant sealed pool) but cards are separated into 4 different groups, dictated by their sleeve colour.
The five colours are White, Black, Blue, Silver and Gold.
White: Basic Lands
Black: (Nearly) One of every non-basic known to mankind.
Blue: All cards with CMC 3 or less. Some 4 drops can fit in here for colour balance.
Silver: All cards with CMC 4+
Gold: Cards that are awesome (the enigma so to speak).
So each of the Black, Blue and Silver cards are setup as their own library. The basic lands are spread out nicely for easy access and the gold cards are stashed away until the game is about to begin.
Rules
Standard magic rules apply with a few exceptions:
- The first card you draw each turn can be chosen to be drawn from either the Black, Blue or Silver libraries.
- When playing a land, you may exile a land in your hand to pick a basic of your choice and put it into play.
- Starting hand consists of 3 black cards, 3 blue cards and a silver card.
- If you would draw a card that is not your first draw for the turn, a 6 sided die is rolled (for each card drawn) and the library you draw from is dictated by the die; 1-2 = Black; 3-4 = Blue; 5-6 = Silver (This was done because being able to know you are drawing 2 4+ drops and not land is back-breaking. The variance was needed to allow card draw to be put in the format).
- Each player is given 1 gold card at the start of a game. It is in the command zone hidden and can be cast at any time.
Example Gold Cards
As you can see, having some of these make you go in specific directions when you have them in your opening hand and not having to worry about mana screw. The ascension becomes a game of trying to take no damage from turn two to turn it on. Destructive Flow you play basics from the start. Or you just have a powerful trump in Karn. Gives the game a different angle to go off of.
It is a great way to get some competitive games without having to worry about deck construction.
If anyone has any queries on the format or if anyone has any suggestions for some cool gold cards I am willing to listen!
