Master.
Put this card in play with 10 nightmare counters. Ravnos get +1 bleed and +1 strength and do not hunt as normal. A Ravnos may steal a blood from another Ravnos as a +1 stealth hunt action. During each Methuselah's untap phase, he or she may move a nightmare counter from this card to a Ravnos. If this card has no counters, each Ravnos burns a blood for each nightmare counter or is burned, then burn this card and the counters. Only one Week of Nightmares may be played in a game.
