I feel that if prowess as an evergreen mechanic was given to a color as another color that green would benefit from it the most.

Green isn't about the non-creature spell life, though.

Flavor aside, I get the impression that green would benefit from it the least... at least in limited. Each set, green usually has either the most creatures, or is tied for the most. That and cards like Lead the Stampede, Advocate of the Beast and Epic Confrontation keep encouraging Green to pack more and more creatures in their deck. If prowess was to come to green, it would require a very big overhaul of the way most designers build.

Green will likely see menace at some point, not prowess. We've already seen prowess in a third color, anyway.

While I don't see prowess appearing on green one drops I think the 2-4 cost range is a good place. I like the idea of prowess being synergistic with ramp spells which often won't have an impact when they're cast. Additionally, would work well with green's enchantment area, albeit white also has a lot of enchantments. I think it's that white is presently supposed to be first in the number of creatures that I figured green needs prowess more than white.

But outside of the occasional love for enchantments, it just didn't fit in Green's current pie to care about noncreature stuff like this.

Green is officially tertiary in menace, after black and red. Prowess is already in three colors, which is another reason we won't see it in green.

I don't think white's history in prowess is necessarily good enough reason to justify not allowing green to have it over white. Due to storyline reasons the red couldn't even have prowess in Fate Reforged, so I feel that greatly skews the viewpoint. I feel this way we may as well justify Ferocious being tertiary for green if ferocious came back.

I like the argument about ramp spells, but I still disagree. For me the biggest reasons are:

• Green already has lots of ways of pumping creatures (eg. the Basking Rootwalla abilities) so one more doesn't make a big difference.
• Green's conditional abilities are usually tied to lands, or creature power, or having lots of creatures in your deck. Prowess refers to casting NON-creature spells. Keeping that out of green established more of a difference between green and other colour creatures, and fits much much better in UR, the two spell colours which benefit from a creature-combat mechanic.
• Most G prowess creatures could probably be in R instead.

If anything, B seems like it could be tertiary, because it often has small creatures that benefit from conditional pumps.

NO. BAD designer! Leave that color pie alone!

We're not saying the color pie isn't fluid in any way, just that changes need to be justified and have to make sense. This one doesn't even make flavor sense, and that's the easiest thing to justify.

I chose a beast type because it was the easiest type to stick on a green body at 3/2. A humanoid race with monk would make sense classwise, or I could just add flavor text like "The northern herd of Krushoks have an unearthly sense of the world." since such seems to justify Ringward Owl. I do have to concede to Jack that prowess doesn't fit green's overall flavor.

­Ringwarden Owl may have weak flavor, but mechanically it's dead on. Mechanically, green with prowess makes no sense, no matter what layer of flavor you slap on.

I had thought that green was no longer number one in sheer number of creature spells, which should have meant that green would have had more non-creature spells (I thought MaRo had mentioned this on Blogatog, but the numbers for the past few blocks had white and green having an equal amounts of creatures). The switch I had thought occurred is why I saw prowess as a way for green to increase the quality/effectiveness of its creatures. I forgot green is secondary in vigilance, which does fit green's creature theme much better than prowess does. Additionally green already shares hexproof with blue and is secondary in flash, so a third evergreen shared between the two seems pretty overboard.

Well, I'm glad you've seen the light, at least. And you're right that green is currently second in creature quantity--white gets the most creatures, green gets the biggest. It might be interesting as a sort of timeshifted effect, though.

White definitely gets the most creatures out of common cards, and the most cards that reward you for having lots of creatures. Whereas green gets the cards that reward you for having a creature-heavy deck like Lead the Stampede and I think it has more cards that reward casting creatures too (but I'm not sure?)

I'm not sure how those stack up against each other -- if green decks end up with more creatures in, but fewer make it to the battlefield, or if white decks have more creatures, but don't have the cards that take advantage of that?
