Mentor Of Champions

When Mentor Of Champions enters the
battlefield, create a 1/1 red and white Warrior
creature token with haste and "Whenever this
attacks alone, put a +1/+1 counter on it".
If a creature you control attacking alone would
cause a triggered ability of a permanent you
control to trigger, that ability triggers an
additional time.
