Kosu, Heir of the Wild Hunt

As long a Kosu is attacking, creature spells you
cast can't be countered and cost {g}{u}{r} less
to cast. (This effect reduces only the amount of
colored mana you pay.)
Whenever a nontoken creature enters the
battlefield under your control, as long as it didn't
enter during a main phase, put a +1/+1 counter
on it.
Surrak lives on through him.
