Unleash the fury of the wild as you outmuscle your opponent with bigger, better, and faster creatures. You'll have the advantage in combat because your creatures will be larger than your opponent's at each stage of the game.

There are several cards in your deck that can help you bust through a strong defense. Even the toughest blockers can't withstand a Vial of Poison. Doom Blade can slice through any single creature, so try to save it for one of your opponent's best. If your opponent tries to gang up on an attacking creature with lots of smaller blockers, your creature-boosting spells will be devastating. Cards like Giant Growth and Briarpack Alpha are perfect for making sure combat goes your way.

Your trump card in a standoff is Enlarge, which gives one of your creatures +7/+7 and trample and forces your opponent to block it with at least one creature. Not only does it deal a massive blow to your opponent's defenses, but it will often allow your other creatures to get through for damage, too. If you need more time to break through, use Plummet, Deadly Recluse, and Giant Spider to hold off enemy fliers.

There are a multitude of powerful creatures in the wide world of Magic™ that would fit right into this deck. Deadbridge Goliath from the Return to Ravnica set is a 5/5 creature for only four mana, and after it dies, you can scavenge it to put five +1/+1 counters on another creature. The Magic 2014 core set features the unstoppable Kalonian Hydra, which begins as a 4/4 but doubles in size every time it attacks. Within just two turns, your opponent will be staring down a 16/16 trampler!
