Jabril, Mentor of the Legion

Flying, vigilance (Attacking doesn't cause this
creature to tap.)
Mentor (Whenever this creature attacks, put a
+1/+1 counter on target attacking creature with lesser
power.)
Whenever you will put one or more +1/+1
counters on creatures you control, instead you
may create that many 4/4 white Angel creature
tokens with flying and vigilance that are tapped
and attacking.
