Nuvera's Presence

Nuvera's Presence enters the battlefield with
four intervention counters on it.
If damage would reduce your life total to less
than 1, then prevent that damage and remove an intervention counter from Nuvera's Presence.
Then, if Nuvera's Presence has no intervention counters on it, sacrifice it and gain 10.
Nuvera is considered the mother of mothers, and she
cares deeply for her young.
