Cleric Of The Bloodied Moon

When Cleric of The Bloodied Moon enters the battlefield, you may discard your hand. If you do,
you may draw that many cards.
Permanents you cast have madness equal to their converted mana cost, minus one.
Whenever you cast a card for it's madness cost,
create a 1/1 Vampire creature token with flying.
The rakdos have perfected the art of killing. Now they
look forward to death.
