Forum:Gravekeeper's Servant and Macro Cosmos

If I were to have a face up Macro Cosmos and a Gravekeeper's Servant on my field, can my opponent declare an attack? I ask this because I once read somewhere that Macro Cosmos would remove the cards sent to the graveyard instead so the opponent couldn't pay the cost. However I can no longer find this ruling, any help would be greatly appreciated.--Whitemon 23:16, 7 December 2008 (UTC)
