Merciful Punishment

When this creature enters, each opponent loses 1 life for each creature they control. Transmute (, Discard this card: Search your library for a card with the same mana value as this card, reveal it, put it into your hand, then shuffle. Transmute only as a sorcery.)

Whenever a creature attacks you, its controller loses 1 life.

Target creature's controller sacrifices it, then creates X 1/1 green and white Elf Warrior creature tokens, where X is that creature's power.
