Corruption

Corruption is a warlock spell card, inducted into the Legacy set, formerly from the Basic set.

Strategy
As a 1 mana card Corruption is one of the cheapest ways to destroy a minion. Corruption will not kill the minion upon cast but will take effect at the start of your next turn.

Be aware that your opponent will see which minion you have cast Corruption upon, and may therefore choose to use that minion to deal as much damage as possible before the next turn - even if it destroys the minion in the process. This still has the desired effect - the destruction of the targeted minion - but may come at the cost of one of your own minions. For this reason, Corruption is ideal when played on a minion with low attack, or when you have a cheap taunt or two such as Voidwalker in position to soak up any attacks.

This card synergizes with the Freeze effect, such as the Battlecry of a Frost Elemental. Since the targeted enemy minion cannot attack, it would die without being capable of gaining value, unless Silenced.

Lore
In World of Warcraft, is a -based warlock spell in the  school that.
