Dryads of Haldezor

Offshoot {g} (You may pay an additional {g} as you
cast this spell. If you do, when this creature enters,
create a token copy of it, except it's a Forest land and
it loses all other types.)

Whenever a Human enters under an opponent's control, you may tap Dryads of Haldezor. If you
don't, sacrifice it.

{t}: Add {g}{g} or one mana of any color.
