{Nim Deathmantle}+ {Ashnod's Altar}+ {Geralf's Messenger} infinite damage
Thats pretty shweet, nice find
Nice. So if I'm understanding this correctly, you sac it twice for 4 mana then pay that mana to get it back with the creature.
And it's not even infinite damage. It's infinite life lose which is even harder to prevent. Nice combo!
