Kara Zor-El

Flying, first strike, indestructible
Kara Zor-El gets +X/+X, where X is equal to your devotion to white. (Each {w} in the mana costs of permanents you control counts toward your devotion to white.)
"I still remember our home world Kal-El. I still remember the Academy, your father's house. It
was still beautiful even as it was breaking from
the inside."
