To quote myself To me , the Primary concern about Splinter Twin was , that 3 CMC spells at sorcery speed were unplayable . annotation Some disapprove this sentence because it is stated like a fact , i am aware of exceptions , but these imply that a general rule exists and creates a very high bar for a 3 CMC sorcery speed card to be viable So this bar for a card to be viable at higher CMC still exists without Splinter Twin . You can ' t think of any card that wouldn ' t see play , because this bar for a card to be viable still exists . You just proved my point . <| sep |> They will eat their own . <| sep |> Not all brand new guests sign up before searching , but I don ' t have numbers on that . I should think that most people , once they have an account , search with it logged in by default . In my case , I don ' t want any new guests to use IB for my place . I find that they do not necessarily have the right expectations and are least likely to properly read the listing and rules .
