Burn
From MTG Salvation Wiki
Burn generally refers a spell or ability that deals direct damage, that is, damage to a target player or creature. Burn spells are most commonly used in aggro decks, and have a low mana cost.
Pure burn decks tend to suffer in the mid-game, when spells have been used up, a hand size is minimal, and there are no creatures to block with.
