Sunafeath Griffin Cubmother

Flying, vigilance (Attacking doesn't cause it to tap.)
At the beginning of your end step, create two 0/1 white Griffin Egg creature tokens with defender and "When this creature dies, create a 2/2 white Griffin creature token with flying."
Other Griffin creatures you control has vigilance.
"From her, they all hatch,
And with her, they all flew"
