"Could Hydroblast fit as a white-blue card? On the assumption that white can destroy any permanent except lands but lands are almost never going to be red?""Maybe, but it sure wouldn't cost one. : )"What about an Un-Card that costs half a white (like Little Girl)and half a blue?

White doesn’t get “destroy target red permanent” cheap.

Hey mark, I wanted to understand the hang ups with the design team not doing more pyroblast/ hydroblast effects. Allowing non blue colors the ability to counter an “opposite” in the color pie seems like a fitting mechanic to allow every color to interact on the stack. Can you do some clarifying on why that isn’t a thing?

Blue can’t destroy permanents, red or not, and red can’t counter spells, blue or not.Having a color be an enemy doesn’t mean you get resources you normally don’t.

The problem with Hybrid Mana is that even if a player intends to use only one color, the creature is still both colors. For example, if I was playing a Mono-Green EDH deck with Dues of Calamity, my opponent could still Hydroblast it because even though I only played green mana for in in my green deck, it still is a red card. I understand that the spirit of Hybrid mana is that a card is either one color or the other, but the rules made them both colors for what I assume was simplicity sake.

But those interactions can happen in every other format when you play a monoblack deck. I don’t understand why Commander can’t work like every other format.
