Sekhen-Ka, the First Anointer

Each creature card in your graveyard has
Embalm. Its Embalm cost is equal to its
casting cost.
Whenever a creature token enters the battlefield
under your control, you may pay {1}{r}{g}.
If you do, it enters the battlefield with your
choice of flying, lifelink, first strike, or trample.
