The card needs to go to exile so the player can refer to the mana cost . Awkwardness ensues if you shuffle the card back into the library . how much did that thing cost again ? Also splitting the mana cost as you want is problematic because it ' s info the player has to keep track of . I would make all costs even then just split them in half . Something like Card Sorcery Meditation You may cast this card for , then exile it as it resolves . You may pay again to put it from exile into your graveyard at any time . You can ' t cast spells while it ' s exiled . You probably don ' t want the spells to be castable for free anyway , since that ' s impossible to balance . <| sep |> where did this meme even come from <| sep |> Because I took a threehour nap earlier tonight .
