Shatter Focus

Choose one—
• Exile target spell. Its controller puts cards
from the top of their library into their graveyard
equal to twice its converted mana cost.
• Tap target attacking or blocking creature, then
remove it from combat. That creature doesn't
untap during its controller's next untap step. Its controller puts cards from the top of their library
into their graveyard equal to its combined power
and toughness.
