Olivia, Frigid Sorceress

Whenever you cast an instant or sorcery spell, for
each {s} that was spent to cast it, you may choose
one that hasn't been chosen this turn—
• Permanents with ice counters on them don't
untap on their controllers' next untap step.
• Olivia deals 4 damage to any target.
• Copy target instant or sorcery spell you control.
You may choose new targets for the copy.
{bull} Put an ice counter on target non-land
permanent.
