Aryll, Gallgolem's Apprentice

Creatures with power 4 or greater can't be
countered.
Whenever another creature enters the battlefield,
put a +1+1 counter on Aryll. If that creature
had power 4 or greater, put two counters on Aryll instead.
"When Gallgolem took me in, he showed me that
beasts aren't as savage and horrible as many
people think."
