Damage

Template:Navigation CRDamage is destruction a creature, Planeswalker, or Player may suffer.

Damage dealt to a Planeswalker causes that many loyalty counters to be removed from it. Damage dealt to a player causes him or her to lose that much life. Damage dealt to creatures is removed at the end of each turn from the creature unless damage dealt to that creature equals or exceeds the toughness which causes the creature to be destroyed and put into the graveyard unless another effect replaces this. An amount of damage larger than or equal to the toughness of a creature is called lethal damage.

While most damage is caused by the combat between creatures there are many cards which can deal damage directly to creatures or players. These cards are usually red, e.g. Lightning Bolt. Damage to a player may be redirected to a Planeswalker provided that the player who controls the source of damage is an opponent of the player who controls the Planeswalker.
