Color slots[edit | edit source]
Color slots refer to a technique that evaluates how much of a deck's mana base is required to support a color on a given turn. The technique is best explained by examples.
For now, let us consider a deck using a basic curve, as referred to in "mana curve", and only basic lands.
Let us start with "60 cards, play first". In these decks, we usually have 24 lands. The first turn color slot requires at least 9 lands. The second turn slot requires at least 8 lands, third requires 7. Conveniently adding up to 24 lands. Hence, this deck could be three colors provided that no spell required more than one of any particular color of mana and that all one-drops were color 1 and all two drops were either color 1, color 2, or both. Three and four drops are free to be any of the colors or combinations there of provided they don't break the 'only one of a given color' rule. This may be notated by C1/C2/C3. For future calculations a final fourth slot would open on turn four if there were space for 6 lands of that color.
If this deck wanted to us double colored mana costs then it would have to dedicate 15 lands to support the cost on turn two, 13 to support on turn 3, or 12 to support it on turn 4. Clearly, doing so absorbs two of the decks color slots. So this deck will be confined to two colors, denoted C1/C2/C1 even though this would support double mana spells on turn two and leave space for colorless land.
For triple cost or above this gets even more restrictive. Triple cost on turn three would require 20 land, or turn four would require 18. The first case restricts us to a monocolored deck when we are only using basic land, C1/C1/C1. The second opens up the elusive fourth color slot, C1/C1/C1/C2, i.e. a splash.
"Reverse Mana Syndrome"[edit | edit source]
Some cards can be so powerful in a deck that players can actually "reverse" the normal way that the colors are represented with lands. If for example a black card is powerful enough to win the game as soon as it is played (or soon after) it will be crucial to have that mana. If the deck has 36 red spells and 4 of these black spells it can be necessary to play with 8 mountains and 16 swamps. Players rarely use this syndrome, even though it is vital in a few odd decktypes.
Manipulating the color balance[edit | edit source]
Besides finding a perfect mix of colors and mana generators there are plenty of ways to twist the balance even further.
- Artifacts: Cards needing no color cause no color problems.
- Hybrid Cards: The fact that these cards may be played from any mix of the it's hybrid colors mean that it is very easy to play such cards, especially if the deck is only two-colored.
- Morph: The ability Morph enables some cards to be played without the use of colored mana. Later they can be activated by the relevant colored mana.
- Multicolored: Few people realise this, but in a deck with two colors and an even amount of the two colors of mana it is far more likely that you can play a multicolored card (Example: Meddling Mage) before you can cast a full-colored card (Example: White Knight). The reason for this is purely statistical. Using such knowledge may press the color balance to the edge of what is mathematical possible.
- Split Card: Increases the chances of casting a spell for the available mana. If the first card of the "split" cannot be cast, there is always a chance that the second may.
