Quote from CatParty »Red likes to force through damage, and hate on Blue. I can see Fore of Red making another spell uncounterable and preventing damage prevention. "Target spell cannot be countered this turn. Damage can't be prevented this turn."
We see this with cards like Exquisite Firecraft, Combust, Inescapable Blaze, etc...
It would also be a cute way of sort of getting Pyroblast into Modern, since it would basically be a red counterspell against blue counterspells.
I expect red force will be like Alliance Pyrokinesis and just damage creatures. These cards appear to be designed as safety valves, not aggro or combo enablers, and a damage splitting spell would accomplish this.
