Death by Bile

Cleric spells you cast cost less to cast. This effect reduces only the amount of colored mana you pay. (For example, if you cast a Cleric spell with mana cost , it costs to cast.)

Sacrifice this creature: Target player loses 1 life.

As this enchantment enters, choose a creature type. Creatures you control are the chosen type. The same is true for creature spells you control and creature cards you own that aren't on the battlefield.

Play with your hand revealed. If you would draw a card, reveal the top card of your library instead. If it's a creature card, put it into your graveyard. Otherwise, draw a card. Whenever a creature is put into your graveyard from the battlefield, return it to your hand.
