Reaper

Reaper are an archetype of Darkness Civilization creatures that were introduced in DM-32 Evolution Saga.

Details
DM-33 Rising Dragon started to give them different abilities for your other Reaper creatures such as staying in the battle zone when they would leave the battle zone (Dark Ikkaku, Reaper Beast), destroy one of your own creatures to destroy one of your opponent's (Deathraios, Cursed Blade Reaper) or drawing a card when they are destroyed (Crooked Digger Reaper)

Many Reaper cards focus on destroying other creatures, or discarding from the hand.

They are the Darkness equivalent of the Light civilization White Knight archetype. Both are rivals fighting a violent battle against each other.
