A lot of effects in this guild will care about the number of specific types in the graveyard, the raw number of cards, or specific abilities that only work if they are there
Creatures you begin to control later in the turn and noncreature permanents that become creatures later in the turn won't get +2/+2 and gain vigilance
Cards like Hero of Iroas, Danitha Capashen, Paragon, and Jukai Naturalist help you cast plenty of auras
Here's a sample around $50: Using dual lands we now have faster, mana-fixing ramp like Skyshroud Claim, and mana-fixing fetches like the Mirage block fetchlands (Rocky Tar Pit)
Pain for All, another new Edge of Eternities card, can create a similar combo
But that means some of the most powerful Magic cards of all time, like Necropotence and Show and Tell are totally fair game
