Tinker's Sharpsword Oil

Tinker's Sharpsword Oil is a common rogue spell card, from the Goblins vs Gnomes set.

Strategy
A more powerful Deadly Poison rolled together with a slightly weaker Cold Blood which applies randomly to a friendly minion. An exceptional card in terms of raw power suitable for aggressive or midrange. The weapon damage buff alone is monstrous if you get it onto any weapon with extra durability like Assassin's Blade, Cogmaster's Wrench, and especially Kingsbane, so don't feel obliged to make use of its combo every time.

It can be played together with cheap Charge minions such as Southsea Deckhand to trigger the combo effect and get immediate payoff even when your side of the board is empty.

Trivia

 * The artwork for this card comes from the World of Warcraft Trading Card Game "Magtheridon's Lair Treasure" series, for the card Surperior Mana Oil.
