how about changing it to only reduce spell damage?
That way, this card doesn't make a combo with GP.
It will give some problems with warden, though. Is that physical or spell damage?
also, as for the unupped, compare to anubis.
This card takes a longer time to prevent any damage,
and doesn't protect from no-damage cc.
It does allow you to buff your creatures, but in an
-
duo, you don't want to buff them anyway (unless with SoW).
That said, anubis costs more to create.
