Swipe

Swipe is a druid spell card, inducted into the Legacy set, formerly from the Basic set.

Strategy
Swipe is a powerful single-target removal card that also acts as an AoE removal card for weaker or weakened minions.

It is also known for making druid extremely strong in the early game and a solid opponent against shamans (because of the fragile nature of the totems), priests (because of their weak early game) and murloc decks (because their health pool is very low).

Note that it affects all enemies, not just minions. This can make it useful for dealing a little extra damage to the enemy hero themselves, especially with some Spell Damage. It also provides you with the option of casting the spell on the enemy hero, which can be a desirable option for end-game nuking or when the spell's AoE damage is sufficient to destroy any minions.

Trivia

 * Swipe is the only damaging effect with an area of effect that is targeted (i.e., that requires the player to actively choose - and be able to choose - a target).
 * Explosive Shot, Grievous Bite, and Meteor are the only other spells that do different amounts of damage to different non-random targets.
 * The artwork for this card comes from the World of Warcraft Trading Card Game "March of the Legion" series, for the card.
