Would these ever be printed?
I like the flavor and it doesn't seem super OP if they are templated like the original and not like pyroblast?
Of course it would likely be in a supplemental set or commander type set vs standard, but maybe bringing back color hosers for draft?
Also I was thinking about a cyclical blast cycle to complete it where white blasts black, black blasts green and green blasts white (for some reason?).
Just a thought experiment.
