Ur'genet, the Flesh United

Whenever Ur'genet, the Flesh United attacks,
blocks, or becomes the target of a spell or ability,
put a flesh counter on target creature or land.
That permanent becomes a 3/3 green and white
Horror creature with no abilities.
{4}{g}{w}: Destroy target creature with a flesh
counter on it, then return Ur'genet to the battlefield. Activate this ability only if Ur'genet
is in your graveyard or in exile.
