>I just think that they shouldn't be almost exclusively for blue, since on-the-stack interaction is way too powerful for one color to have
what they really need to do is print a fuckton more Split Second cards; if they want to keep counterspells in blue then they need to give everybody else ways to shut down the stack. It's not a true counterspell, but if somebody's playing a 2-card combo, being able to play a Split Second card halfway and make it fizzle is often good enough anyways.
