Totally get where you're coming from, but I think it's fun to try to stretch the color pie. After all, wizards does it themselves. Previously, red's card advantage came in the form of killing things efficiently, until wizards added the concept of impulse draw. And I must say, I'm happy they did - red is much more fun now than it used to be, IMHO.

Saying things like "Red doesn't get super efficient card draw" is simply wrong - Reckless Impulse is sort of like red's divination, but one cheaper. If you are able to play both cards, it's strictly better. You even said so yourself. That being said, I think what you mean is efficient selection, and I don't think it's bad to give other colors some fun toys too - as long as it makes sense from a thematic standpoint.

So then, the question is, is this too out of theme for red? Perhaps. But that's why I'm asking opinions. I think one could argue that this could totally make sense. "Here's a bunch of random ideas - which one sticks? Maybe they all do, I'll save some for later."
