Contest of Valor

When Contest of Valor enters the battlefield, if
you control Vanner, the Valiant, untap her and
put a +1/+1 counter on her.
Whenever a legendary creature you control attacks
or blocks, you gain 2 life.
Legendary creatures you control get +1/+1.
The roar of the Lion was the rallying cry of her armies.
But her low growl in a test of arms was enough to shake the core of even the stoutest of men.
