Urla, Protector of the Meek

If a Squirrel creature you control with power less
than or equal to Urla, Protector of Meek would
die, you may instead sacrifice two Nut tokens and prevent all damage that would be dealt to that creature.
{t}, Add {x} Nut tokens, where {x} is the number
of Squirrel creatures you control.
He is wise and provident, for he has seen many eras
and fought many wars.
