Norek, Myrkul Battle Priest

Whenever an Aura enters the battlefield under
your control, if that Aura was black, each
opponent loses 2 life. If that Aura was white, you
gain 2 life. If that Aura was green, target creature
gets +2/+0 until end of turn.
Whenever one or more Auras you control would
be put into your graveyard from the battlefield
return up to one other target Aura from your
graveyard to your hand.
