Dark Trauma

Put the top half of your library, rounded up, into your graveyard. You lose life equal to the number of land cards put into your graveyard this way. Creatures your opponents control get -X/-X until end of turn, where X is the number of creature cards put into your graveyard this way.
Phyrexians force some who try to fight back once captured to ingest inkmoth serum, giving them traumatic visions and shattering their will to resist.
