This would not be that much of a "shift" since it doesn't affect black's mechanical identity at all. Since black already gets a 2/2 aka the "bear" this isn't changing anything. You could say that (((Brutal Combatant))) is the same thing, but there I would note that it's actually pushing white (taking green's place?) to be a (lower end?) fatty color.

Shift? No this isn't a color shift. I just need a vanilla for each color. The theme for the set isn't like time spiral it's focused on choices.

Oh. There have been so many color shifting projects that I jumped to premature conclusions...

That's OK. The name of the set probably confused you.
