The Fifth Dawn game expansion from Magic: The Gathering was released in 2004 as the third set in the Mirrodin block. Despite its name, it doesn't feature 5 decks, but only 4. Three of them are bicolored and the last one features all 5 colors.
Stampede is the name of the bicolored decks, and the colors used are indicated on the box: red and green. Lands and Creatures are abundant in this deck of 60 cards. These two card types feature 23 and 26 cards respectively.
You'll also get 6 instants, 1 Enchantment, and 4 Artifacts. The whole expansion relies quite a bit on artifacts, hence they're more abundant than in other expansions.
