[deck title=Immortal Constellation, by Ken Crocker] [Creatures] *4 Boon Satyr *4 Herald of Torment *4 Grim Guardian *4 Nyx Weaver *4 Courser of Kruphix *2 Mogiss Marauder *4 Satyr Wayfinder *3 Nighthowler [/Creatures] [Spells] *4 Commune with the Gods *3 Immortal Servitude *2 Strength of the Fallen [/Spells] [Lands] *4 Temple of Malady *4 Overgrown Tomb *2 Mana Confluence *6 Swamp *6 Forest [/Lands] [/deck] Obviously, this deck is extremely similar to the B/G Dredge decks (both with and without [card]Strength of the Fallen[/card]) and B/G Constellation decks
