(The Not So) Brave Sir Robin

{g/w}: You may return all knights you control
to your hand. You may play them without
paying their mana cost.
He was not in the least bit scared to be
mashed into a pulp, Or to have his eyes
gouged out, and his elbows broken;
To have his kneecaps split, and his
body burned away; And his limbs all
hacked and mangled, brave Sir Robin!
