King Gilgamesh, Ruler of Uruk

Whenever a non-Human creature you control attacks, look at the top six cards of your library.
You may put a Human creature card from
among them onto the battlefield tapped and attacking. It gains indestructible until end of
turn. Put the rest of the cards on the bottom of
your library in a random order.
"We will be radiant on the dawn of victory, and tether
a generation with that light!"
—King Gilgamesh
