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.

I just want a Brown Elemental Blast. You know, for the poop jokes.

I just thought about this the other day. And Green needs one too....it can be for a colorless spell or colorless permanent. Some juice vs eldrazi/shops, and green is an anti-artifact color anyway.
