Slave knight Gael

Human - Devour 3 : When Gael enters the battlefield, you may sacrify any number of Human creatures. Put 3 +1/+1 markers on Gael for each
creature sacrified this way.
A slave knight used in the front lines of war, for he is
undead. Tasked by his lady to retrieve the Dark Soul
of Humanity, he beseeches it through all means.
