Nami, the Tidecaller

{1}{g}: Target other creature you control gets +1/+1 until end of turn and if your
opponent controls a creature it instead gets +2/+2 until end of turn.

The Marai's Tidecaller is trusted to trade an abyssal pearl for a moonstone. The moonstone's light protects the Marai from the creatures that crawl from the abyss.
