If stomping your opponent into submission with huge creatures sounds like your idea of a good time, welcome to the beefy world of the Devastation deck. All the ingredients you need are right here: big creatures, bigger creatures, and ways to get enough land to play them. Throw in some damage spells to eliminate your opponent's blockers, and you've got a recipe for a good whompin'!
While Beasts are obviously the main focus of the deck, you'll find most of them too expensive to play without a helping hand. One of the most important cards in the deck is Explosive Vegetation. Using it to fetch two basic lands from your deck and put them into play increases your mana resources dramatically. Wirewood Elf and Elvish Pioneer also help get your monsters on the table as quickly as possible. With the right draw, you can actually have six to eight mana available on your fourth turn.

Even if you do find yourself hurting for mana early in the game, you'll still be able to play most of your Beasts. How? You can play a Beast with morph face down as a 2/2 creature for only 3 Mana mana. Your opponent won't know how much of a threat your face-down creatures are, and some of them are cheaper to turn face up than they are to play from your hand. Imagine your foe's face when your 2/2 critter suddenly becomes a 7/6 Towering Baloth! If you need to, don't be afraid to use Barkhide Mauler's cycling ability to search deeper into your deck for land. You'll draw more Beasts later to make up for it, especially with the help of your Wirewood Savages.

Most of the Beasts in the deck can be swapped out for your own favorites. Consider Beasts with morph or cycling, which add variety without straining your resources. Krosan Tusker is a good choice because it provides land early or a huge creature late. Hystrodon is a 3/4 trampler with morph that lets you draw a card whenever it deals combat damage. And Ravenous Baloth is another 4/4 Beast that lets you sacrifice a Beast to gain 4 life. As long as it's big, it'll find a home in Devastation.
