Death Pit, allies with 4 HP or lower get instantly destroyed by this benched trap card upon being played. It costs 1 black/2 normal energy to play, and is good against red, yellow and green (quantity, not quality) decks, since they contain mostly low-stat allies. Any allies with HP over 4 can bypass this trap, so for blue develop decks it's mostly ineffective.
Strong against: weak allies, decks with low ally count.
Weak against: strong allies, ally-heavy decks.
