Peggy Carter

Whenever another nontoken creature enters
the battlefield under your control, bolster 1.
(Choose a creature with the least toughness
among creatures you control and put a +1/+1
counter on it.)
"Even if the whole world is telling you to move.
It is your duty to plant yourself like a tree, look
them in the eye, and say "No, you move.""
-Peggy Carter
