As far as I'm aware, the colorless hybrid cards in Shadowmoor (Like spectral procession) all used multiple color symbols without any non-color/non-hybrid symbols in them. The cost on them all looks very aesthetic. What about a cost like or ? Are costs like this appealing? Does it matter? I'm trying to incorporate colorless hybrid, but find myself generally disliking costs that look like that. However, I feel constrained if I need to only used hybrid symbols in a hybrid cost. Am I just being neurotic?
