Child of Amara

Whenever you cast a Curse spell, draw a card.
Other Curse spells you control have
"Whenever a player casts a spell, that player
loses 1 life." Whenever a player loses life, if
that player has three or more Curse cards
attached to them, you may search your library
for a Curse card and put it into your hand.

"Those who cross me shall suffer a curse most
dire, and their screams shall be music to my ears."
