Give a friendly minion +4/+4 until end of turn. Then, it dies. Horribly.
We cannot even describe how horrible the death is. It's CRAZY bad! Maybe worse than that. Just don't do it.
 How to get
|Golden Power Overwhelming||400||50|
This card works well in conjunction with High Damage/Low Health Charge cards like Wolfrider to do large amounts of damage in one turn. Another good combo is using this card on creatures with Windfury.
Power Overwhelming is also a noted combo with the card Void Terror. To execute the combination with Power Overwhelming you need to play Power Overwhelming on a minion you intend to have Void Terror consume. After casting Power Overwhelming, attack with the targeted minion (not required for the combo but generally advised). Then finally play Void Terror adjacent to the targeted creature, resulting in the Terror retaining the bonus damage and life that was granted by Power Overwhelming.
Power Overwhelming does not have any specific lore in the warcraft universe, although its character fits well with the warlock class. However, the name itself may well be a reference to Starcraft. In Starcraft, Protoss Archons says the phrase and it is also one of the game's cheatcodes, activating a godmode for the player's units, making them invulnerable to attack (and kill instantly), which is ironic when considering Power Overwhelming kills the minion it is cast on.
