Jjhado-Ki, Hellcaller

Haste
When Jjhado-Ki attacks, you may sacrifice a land
and pay 1 life. If you do, return a creature from
your graveyard to the battlefield tapped and attacking. Sacrifice that creature at the beginning
of the next end step.
Only the most tormented of souls can hear his unspeakable orders. Only the most tormented of souls
will obey them.
