This could jump to $20 or $30 and no one would be surprised, right
But it's great to know that we can go infinite in a Rakdos sacrifice deck without dipping into other colors
Explore, Rampant Growth, heck even Natures Lore or Mind Stone would all be great
Just a quick aside, Skullclamp is one of the most broken and powerful cards ever created

Before I go into more detail about U/W Spirits and why Im a fan of the deck, heres my latest decklist, which Ill be referencing throughout the article: Creatures (31) 2 Phantasmal Image 2 Geist of Saint Traft 4 Drogskol Captain 4 Rattlechains 4 Spell Queller 4 Selfless Spirit 4 Mausoleum Wanderer 3 Remorseful Cleric 4 Supreme Phantom Lands (21) Spells (8) Also, heres a Bant Spirits decklist for reference, courtesy of Johnathon Schrader, who finished first at the StarCityGames.Com Invitational Qualifier in Roanoke, Virginia this past weekend: Creatures (30) 1 Birds of Paradise 4 Noble Hierarch 2 Phantasmal Image 4 Drogskol Captain 4 Rattlechains 4 Spell Queller 3 Selfless Spirit 4 Mausoleum Wanderer 4 Supreme Phantom Lands (22) Spells (8) As you can see, the reason to add green to the Spirits deck is to play Collected Company, an instant-speed threat that pairs nicely with the flash creatures from the Spirits deck
