I like to break down cards for decks by "meat," "potatoes," and "vegetables" as an analog to what cards do for a deck
On the Nintendo DS, they did a great job emulating both the anime and card game
On the other hand, Discreet Retreat is another very powerful, but very narrow card: For 4 mana, you get ramp, color-fixing, and card draw on a land enchantment - but once again only if you're dealing with outlaws
Edge whitening, corner wear, and centering (how even the borders are on each side) are the raw ingredients of the condition estimate, so cropped edges mean a vaguer value range
Wheeling the table again and again and saving a ridiculous amount of mana on your spells is some of the most fun I've had in Magic
