This would get a red flag for being a common that can kill two other creatures, getting a 3-for-1.

(Being red-flagged does not automatically mean "change this card", though. It just means "be careful with this card, check whether that's really what you want to do, and don't have too many like it at common." 10%-20% of the commons in a set can be red-flagged in a typical expert set.)

Removing the "Up to" mind you makes this a funny potential land-mine if your opponent isn't playing targetable creatures :)

I know it can potentially kill 2 other creatures, thought it was quite fair for it's price though and needs a lot of set up to really kill 2. Maybe make it more expensive or mana demanding, like 3BB.

No, I think power-level-wise this is fine. Most of the time it's not going to give you a three-for-one. (Though it could be nasty in second main phase after a combat where you pushed through some damage at the cost of making what looked like some unfavourable trades.)

I don't think the price needs to go up. That's not what red flag means. It's not cards you need to nerf - just cards you need to be careful about. (Vitenka's nerf, while funny, doesn't actually remove the flag.)

Yeah, mine is just for funsies. No real problm with the card. It's good, but not horribly so. As Alex says - just be a bit careful not to put too many similar things in at once.

One probably bigger problem : Your feast mechanic puts +1 counters on things. +1 counters and -1 counters in the same set is displeasing.

She was a "Combo" piece for the old Feast mechanic, which triggered at the end of turn. Attack, then if no creature died play her to kill a wounded creature and get the counter at the end of turn. Is pretty easy though and doesn't really fit the mechanic. Eating your prey after a fight is fair game and all, but when the fight is already over? Feels weird. @Vitenka: Don't worry, it's just -1/-1 until end of turn, not -1/-1 counters. Both in the same set, or even same rotation is a big nono.

Both +1/+1 counters and -1/-1 counters in the same block is a nono, but there's no prohibition in having them in adjacent blocks. Otherwise you'd need two blocks with neither either side of a -1/-1 counter block.

I know it happened before, but it having 2 blocks with neither shouldn't be too hard, even if +1/+1 counters are almost ubiquitous these days.

Fair enough; again; not a show stopper, just a slight worry.

And I didn't mention the name - which is just so fantastic. Not something that would make it into a real set; but do keep it. It's great.
