Crystalhide Wurm

Trample, hexproof
If a spell would target Crystalhide Wurm or another creature you control, you may copy that spell and choose new targets for the copy.
{g}{w}: Target creature gains hexproof until end of turn.
Its shimmering hide makes even the most precious of the jewelry hanging from its body, offerings from native peoples who revere it as a god of nature, seem dull and worthless.
