Dwarves are a creature type most closely associated with red and white, with many cards supporting artifacts, Equipment, Vehicles, and Treasure. Dwarf decks can therefore range from straightforward typal aggression to elaborate artifact engines.
Dwarven Recruiter can stack your library with exactly the Dwarves you need, while Dwarven Bloodboiler turns otherwise idle Dwarves into large combat bonuses. Magda decks can also use cheap Dwarves as a remarkably efficient Treasure factory.
