Magic (card game)
Most spells are one of five colors: white, blue, black, red, and green. To play a spell, at least one mana that is the same color as the spell is needed. Players normally get this mana from "basic lands": "plains" for white, "island" for blue, "swamp" for black, "mountain" for red, and "forest" for green. Each color has strengths and weaknesses, with white magic dealing in protection and defense, blue magic dealing with manipulation and thinking, black magic dealing in death and greed, red magic dealing in fire and emotion, and green magic dealing in strength and nature.
