Sona, Maven of the Strings

Whenever you cast a white noncreature spell,
each player gains 2 life.
Whenever you cast a blue noncreature spell, each player draws a card.
Whenever you cast a green noncreature spell,
each player may pay {2}. If they do, that player searches their library for a basic land card, reveals
it, and puts it into their hand. Then, each player
who searched their library, shuffles it.
