Nonsense Color Pie: Creatures
Pink creatures often create value evenly for each player or specifically aid your teammate, then their other abilities allow you and your teammate to better make use of the resources they generate.
Yellow creatures have a lot of on attack effects, as well as effects that target randomly. They occasionally have abilities that cause or benefit from damaging yourself (like on Lightning-Flinger) or discarding cards.
Teal creatures often have complicated or convoluted abilities and focus on using consolidating power into a few large creatures, often through abilities that buff themselves when you control or sacrifice smaller creatures.
Orange creatures usually destroy themselves or are particularly weak. They gain strength or create value when they or another creature dies.
Brown creatures have relatively simple, though diverse, effects ranging from discounting your spells or destroying an opponent's permanents to providing keywords to all of your creatures. They try to do one thing, really well. If they only have keyword abilities, they usually have aggressive stats to compensate.
