Galadriel, Lady of the Wood

Whenever a creature with power 2 or less enters the battlefield under your control, you get an experience counter.
At the beginning of combat on your turn, put X +1/+1 counters on another target creature you control, where X is the number of experience counters you have.
"Even the smallest person can change the course of the future." -Galadriel to Frodo Baggins
