The average number of lands used is 24.5.
Green (forest) is the most common type of card used in these decks, followed by Red (mountain) and White (plains). For special lands I allocated 50 percent to one of two colors for two-color lands, and 20 percent to each color for special lands that can add to any color. Evolving Wilds stands out as the workhorse of special lands.
Here are the non-land cards ranked from most common to least common. The difference between the lands and these cards is 28 cards, and that means I dropped two or three artifacts while coming up with these numbers. This is not a big loss. The objective here is to highlight the workhorse cards.
The most commonly used cards are shown here. These 2,692 cards account for half of all of the non-land cards used in these 103 tournament decks. Most of these decks are Garruk decks.
Its no surprise that Avacyn's Pilgrim is one of the top cards: most of these decks have green cards, and many also have white cards. Avacyn's Pilgrim only costs one forest land to cast and can add one plains mana card to your mana pool.
In this next batch we find cards that were used sparingly, including a handful of Mythic Rares.
These cards are found as a playset and indicate one player's choice.
...and these cards saw very little play in such a large field of decks.
