Aria, the Mirror Sage

If you would pay a cost as part of a triggered
ability, copy that ability. You may choose
new targets for the copy. (You still have to
pay the cost for the copied ability.)
Whenever you cast an instant or sorcery
spell with converted mana cost 1 or less, you
may pay {u/r}. If you do, copy that spell. You
may choose new targets for the copy.
