Masked Revolutionary

Dethrone (Whenever this creature attacks the player with the most life or tied for most life, put
a +1/+1 counter on it.)
{w}{b}: If Masked Revolutionary isn't a Spirit, regenerate it. It becomes a Spirit and it gains flying. (It's no longer a Human Rogue. This effect lasts indefinitely.)
"Beneath this mask there is an idea that
no one can steal it."
