Gilgamesh, Fallen Guardian

This creature is all colors.

Vigilance, Flying, Menace, Double Strike, Trample

{5}: Regenerate Gilgamesh. (The next time this permanent would be destroyed this turn, it isn't.
Instead tap it, remove all damage from it, and
remove it from combat.)

Gilgamesh must attack each turn if able. If it can't, sacrifice Gilgamesh during the end step.
