If one or more age counters would be put on a permanent you control, that many plus one age counters are put on it instead.
Whenever you cast a spell or activate an ability
that has {s} in its cost, tap target creature you
don't control. Snow creatures you control gain
+1/+1 until end of turn.
Even after Heidar's death, many creatures adapted to
what he brought, some even flourishing in it.
