@mimimmo98 not sure what you mean by I cannot end the game with a single stack. If I have normally 8-9 creatures in GY, for arguments sake, 3x
blood artist, 1x Visera Seer, 5x other creatures, we bring them back with
Rally the ancestors. Once all of them are on the battlefield, you sacrifice one creature, they die and go to the graveyard, opponent lose 3 life and you gain 3 life as
blood artist triggers. Sacrifice 7x creatures to deal 21 damage and gain 21 life. Game
ends.
But after board, one shot graveyard hate we are still ok with it, as we got our 1/1 beats and can refill graveyard quite easily. But sideboard that kills us most is
rest in peace and
leyline of the void, most of the time we can never win (unless we draw a timely
Knight of Autumn).
