If it's your turn, you control Coram, and another player has permission to play a card in a graveyard that was put there from a library this turn (perhaps because it's an instant card they own that has flashback), whoever gets priority sooner will have the first chance to play that card. In most cases, this will be you, since the active player receives priority after a spell or ability resolves.
