Kitava, the Insatiable

Indestructible, menace, trample
When Kitava, the Insatiable is put into a
greveyard from anywhere, create a 0/1 black
Kitava's Heart creature token with "At the
beginning of your upkeep, sacrifice this creature
and return target card named Kitava, the
Insatiable from your graveyard to the battlefield."
"An endless pit of gnashing teeth and churning guts."
