Lan, Descendant of Malkier

When Lan enters the battlefield, distribute X +1/+1
counters among any number of creatures you
control.

Whenever a creature you control with a +1/+1
counter on it deals combat damage to an opponent
or planeswalker, create a 1/1 black and green
Human Soldier creature token with training.
(Whenever a creature with training attacks with
another creature with greater power, put a +1/+1
counter on the creature with training.)
