After 1 Counter Trap Card you control has been activated and has resolved, you can Tribute 1 DARK monster to Special Summon this card from your hand. If this card is Special Summoned in this way, destroy 1 card on the field.
Special summoning this card is relatively easy since you just need to "activate" a counter trap card. You do not have to negate/destroy a card your opponent uses by the counter trap card. Also there are useful low level DARK monsters.
Running this guy with counter traps makes you actually look forward to the opponent's backrow. You don't even care if you lose the duel, you already feel like you win when you negate the opponent's card and get this guy out.
