Quote from user_938036 »Unsummon, shock, and terror are all standard maindeckable. Which I think is antithetical to what you wanted. While white is getting such an unplayable card that I doubt it would be played. Green is weak but not bad like white, the card it gets is too specific to make this guy a main deck card and there are almost certainly better sideboard options.
