Rogal Dorn

When Rogal Dorn enters the battlefield create a 0/4
White Wall Artifact creature token with Defender
and Reach.

At the beginning of your end step if a Wall you
control blocked an opponent's creature this turn and
was not destroyed, create a token copy of that Wall.

{2}{r}{t}: Choose a Wall you control, that Wall gains Deathtouch until end of turn.
