Magic: The Gathering features a variety of card types defined not just by categories like instant, enchantment, and artifact, but also by gameplay role. Instants and sorceries can be anything from mana ramp to defensive spells to card draw, but when instants and sorceries can neutralize a single creature, they are considered removal. "Removal" can also apply to hitting other permanent types, but in the MTG community, "removal" usually means taking out creatures. This is vital in all formats—including the Commander format.
