Booby Trap,taking out strong allies with 5 HP or more. It has the same cost as Booby Trap at 1 black/2 normal energy, but works against the opposite type of deck.

Strong against: strong allies and quality decks, as well as blue develop decks and decks with low ally count.
Weak against: filler and quantity decks.
