Sal & Las, Brides of Belial

At the beginning of each opponent's upkeep if that player has one or fewer cards in hand, that player looses 4 life, if that player has seven or more cards in hand that player discards until they have six cards in hand instead.
Whenever three or more cards are put into an opponent's graveyard from anywhere, that player discards a card from their hand.
"We wait... for soon he will return."
