Kutos, Stonelife Mystic

As long as you control a creature with power 4 or greater Kutos, Stonelife Mystic has Hexproof.
{x}{g}: Untap target noncreature land you control,
until the end of the turn it becomes an X/X land
creature with haste, it is still a land.
"When you insult the land, don't be so surprised when
it fights back."
