Awakened One, the Curious

Curiosity — When an opponent gets an emblem
or gains life, place two +1/+1 counters on
Awakened One.
Rebirth — When Awakened One dies, if it isn't awakened, return it to the battlefield at the start
of the next end step with the same number of
+1/+1 counters it had before death and it
becomes awakened. As long as Awakened One is
awake, it loses curiosity and gains trample and swampwalk.
