I like how a big deal was made out of menace being primary in black and not red, yet there is only one black menace (which sounds rather racist) card in Origins and it's at rare, with the others being a red common and uncommon. Also, a red reach card. What.
Also, Orchard Spirit reprint after MaRo complained about how "can't be blocked except by creatures with flying or reach" (psuedo-flying) shouldn't be in green.
On another note, I reached a revelation with my decks that I make to teach beginners (which I have only done once so far): enemy color decks are more interesting in this case than ally colors, especially with prowess now in red/blue. I'm remaking them right now. Black/green has more or less been settled. The structure is the way it is because I took my old black/blue deck and shoved the modifications on the end.
