When I'm teaching Magic: The Gathering to a new player, one of the things I usually give them early on is a run down of each of the different colors and its pros and cons. I usually try to come up with 2 sentences and no more than 3 example cards to describe the color. Normally, I use descriptions that are something like this:
Red: Uses the power of fire to damage life totals, creatures, and destroy lands/artifacts. Has trouble dealing with enchantments, flying, and tricky spells. Examples: Shock, Shatter, Demolish.
Black: Uses the power of death and evil to profit from other misery with powerful removal, creatures, discard spells, and detrimental enchantments. Has trouble dealing with enchantments, vulnerable to removal, and has slightly weaker creatures. Examples: Doom Blade, Mind Rot, Sorin's Thirst
Blue: Uses the power of the mind to manipulate the field of battle by drawing cards, countering spells, messing with opponents' plans in general, and playing flying creatures. Has the weakest creatures in the game, even though it has many of the best flying creatures. Examples: Divination, Cancel, Darkslick Drake (or any other good flying creature)
Green: Uses the power of nature to grow and expand until its massive creatures are too much for opponents to handle. Good at dealing with artifacts/enchantments, and has strongest creatures in the game, but also has worst flying creatures and very little removal. Examples: Llanowar elves, Leatherback Baloth, naturalize
White: Uses the power of life and justice to play powerful creatures, life-gain spells, sweeper spells, small creatures, and good defenses. Second best in flying and creatures overall, but weak against ?????? Examples: ?????
While these are rough examples that could all use a bit of polishing, I definitely feel like my understanding and explanation of white looks the weakest. Currently, I look at white as the 'all-around color' with fewer strengths and weaknesses than the others, but I'm having trouble characterizing it in more specific ways.
How would you explain the pros and cons of the color white to newcomers to MTG? What example cards and general characteristics of white decks would you include? What might you add to my other explanations to make them more helpful and accurate, but still keep them clean and concise?
