Each game represents a battle between wizards known as «planeswalkers», who employ spells (artifacts, creatures, sorceries, etc.) depicted on individual Magic cards to defeat their opponents.
Most spells come in one of five colors, they are: white, blue, black, red, and green. To play a spell of a given color, at least one mana of that color is required. This mana is normally generated by a basic land: plains for white, island for blue, swamp for black, mountain for red, and forest for green. The balances and distinctions among the five colors form one of the defining aspects of the game. Each color has strengths and weaknesses based on the «style» of magic it represents. Some spells require colorless mana, it means you can use any color of mana to cast those. Some lands give colorless mana, it can be use only for colorless requirements.
Grixis is a type of deck combination of blue, red and black spells. Here is an example of a Grixis Deck I’m working on it.
