The "Sole Domination" deck focuses on creatures with the exalted ability. If you attack with exactly one creature, each of your creatures with exalted boosts that creature by giving it +1/+1 for the turn—and you'll still have the other creatures back on defense! The most fearsome attacker of all is Nefarox, Overlord of Grixis. If this 5/5 flying Demon attacks alone, not only does it get all the exalted bonuses (including its own), but it also forces your opponent to sacrifice a creature.

The deck's other creatures are particularly suited to take advantage of those bonuses. Vampire Nighthawk has flying, lifelink, and deathtouch. Liliana's Shade let you spend black mana to make it bigger in addition to any exalted bonuses. Veilborn Ghoul makes it almost impossible for you to run out of creatures: it comes back to your hand from your graveyard when you play a Swamp!

Although the exalted ability appears in black as an expression of powergrabbing, in white, exalted is an expression of communal support. Among your white cards with exalted is Angelic Benediction, an enchantment that not only boosts your solitary attacker but also taps a potential blocker whenever your champion attacks.

For even bigger boosts, try adding more cards with exalted to your deck. Cathedral of War is a land with exalted, and Sublime Archangel gives each of your creatures exalted, even if they already have the ability—and each instance works independently! Disciple of Bolas takes advantage of all those temporary boosts to cash in your creature for extra life and extra cards. And the planeswalker Liliana of the Dark Realms harnesses the power of Swamps for a variety of delightfully evil purposes.
