Yet another example of a throwaway line that needs further explanation that I have to ask because you didn't simply include it in the above.
Why was the double red requirement a problem?
Why "yet another example?" It's not as though I forgot to include an explanation of some sort. It's not even a "throwaway" line. What am I throwing away?
The double red mana requirement has been an continues to be a problem for Fork and many other cards because it makes them more difficult to cast in a multicolored deck (and/or a deck that uses sources of colorless mana such as Wastelands). This is not complicated. I did not exclude it by accident or out of torpescence. I excluded it because it is very basic.
One good example is Counterspell. Mana Leak, from its effect, seems strictly inferior to Counterspell. The only advantage it has is that it does NOT have a double colored mana requirement. And I have seen Mana Leak favored over Counterspell in many decks.
Fork is a nice spell. I've used it a lot myself. But most decks that would really appreciate its effects are not monored. Fork for 1R would have seen more use. We'll probably never see such a spell, but a blue Fork might be even better.
I'm still not sure how much play Twincast will see. Fork isn't as playable as it once was, and this was probably taken into account before it was reprinted in blue. But we'll see...
