I really like the Stingscourger ability. I know it's supposed to be an alternate take on Magic, but I'm a bit dissapointed that Wizards didn't follow that up in a later set.

This feels so weird.

Also, the devils are the more sentient red creatures (I think). I don't really picture the yetis having classes. But that can be up for debate.

Mmm... I do like the idea of red bounce, but at the moment it's still pretty clearly alternate-universe. I note that Planar Chaos was careful to include at least three cards in each of its major colour bleeds (white countering, blue vigilance, black tapping, red bounce, green haste and flying, etc) - so Stingscourger was joined by Aether Membrane and Dead // Gone. I wonder if we should do the same if we want to extend red's pie back into this area. (They don't all have to be at common of course.)

I do like the idea of version of Chaos Warp that returns to hand instead of shuffling it into the library. It would have to be opponent only, of course, to prevent some possible shenanigans.

I agree we don't want to shift the colour pie unless we're sure it's a good idea. It's too easy as an amateur designer to break the colour pie because something feels right, and not realise whether or not there were good reasons for how it was (or not even realising you're shifting the pie, like when we put lifelink in green or hexproof in white because it feels like they should have been there all along).

However, I think other-bounce in red probably is a good idea. I think people agree red limited can get a bit samey? And wizards have been cautiously shifting some other things into red. And that sort of shift-the-problem-into-the-future tempo advantage is very red. So I like the idea of officially shifting it into red.

But I don't think it does need the planar chaos treatment. I think planar chaos was careful to show at least three cards for contrast, to show where the new pie space was, rather than just what direction it had moved in. However, when wizards have printed a non-planar-chaos new mechanic in red (intimidate and looting), they've generally started to do so with just one card, because that's enough to indicate the direction they're going in, and it expands the pie a bit without committing them to how far it might move in future.

So I don't know what's best, but my best guess for "official policy" would be to print one red bounce spell (or possibly one common and one other) and see how it was received. I think it'd be ok to print more if we decide they're what the set needs (which is quite possible), but not the default.

The more I think about it, the more I like the idea. It is funny, though, that red would be getting, within a small time frame, two abilities that were previously blue (looting and bounce).
I could go for either straight Unsummon-style bounce, or a some variant:

Whiplash
Instant
Return target creature you don't control to its owner's hand. ~ deals 1 damage to that player.

Warp Fracture
Instant
Return target permanent you don't control to its owner's hand. That player reveals a card at random from his or her hand. If it's a permanent card, he or she puts it onto the battlefield.

"red would be getting, within a small time frame, two abilities that were previously blue"

Yeah, we don't want to overdo it. I think we have the luxury of pushing it a bit further in a nonofficial set, since people won't yell at us if we leave enemy-bounce out of magic in future :)

Come to think of it, a few years ago, red got fork from blue. And ages ago got fast mana from black.

I think the defining thing with red bounce is to be (a) enemy-only and (b) sorcery speed, so it functions aggressively. Since blue doesn't get that exactly, I'm inclined to vote for the simplest versions to start with, although it's good to brainstorm alternatives too.

The chaos-warp effect is interesting. Can you make a card for it? I suspect it'll end up at uncommon, but it'd be a good way for red to interact with a blocker. I'm torn between several possibilities:

• polymorph which only works on enemy creatures
• polymorph with is cheaper, only works on enemy creatures, always upgrades them to more expensive creatures, but puts them onto the battlefield tapped
• sacrifice, replace with random creature from hand
• bounce to hand, put random permanent card onto the battlefield
• link's original wording.

But but.. Fork was always red!

While I think we can do just one, if we are only doing one, I think we want that one to be a simple execution of the ability. If we chose polymorph other, we'd be saying that we think polymorph other should be red, but not other bounce. I like polymorph other tricks... but I think that, if we want that, we should probably print a 'bounce other' in common first, to point to the fact that we're cool with the basic premise, before getting into the wackiness.
