If you were hesitant to go for an unfair approach in Cube before now, hopefully you are coming away with the tools to identify and take advantage of some of the sideways strategies available, and become the unfairest of them all
I doubt Crdan the Shipwright will keep such a high price for long, but Id bet itll still hold some value
Or, using Thrasios, Triton Hero and its partner ability to make all kinds of different colored decks
In Standard, theres Phyrexian Arena and Mindsplice Apparatus
Golgari can do it too, though, and has access to a bunch of good commanders like Carth the Lion or partner decks with Reyhan, Last of the Abzan
I like it a lot in four or five color decks in this role, but in three or fewer colors it hardly seems necessary
