Renown/Cipher support

Does this need the +1/+0 bonus?

what's the case against it?

Without it is seems real weak. Heck, I would be surprised to see this not be a 23rd card. I would argue to make it +2/+0 before removing it.

That said, I haven't playtested it yet, so it is hard to see its impact.

Basically in limited your right this is filler. But any 1cmc cantrip can't be pushed due to constructed.

­Nighthaze, Slip Through Space or Leap etc. None of them give a +1/+0 bonus. While cards like Defiant Strike Give the bonus but no keyword.

I'd much rather push this and remove the cantrip effect. Unless we need it due to card flow in black.

­Distortion Strike.

The problem has more to do with how black has historically had very few commons instant/sorcery cards that grant evasion (especially compared to how often other color grant keywords) for us to refer to.

Black seems to be getting more +n/+0 effects recently, though (Touch of Moonglove, Boon of Erebos, Cruel Feeding, Unnatural Endurance...), so I think it ultimately could go either way. It's just hard to judge how good giving menace is.

See, Doombringer, I think this card threads the needle between the effects you listed above.

Granting Menace at instant speed means nothing. So, its a sorcery. I think that speed is a big enough deal to give a slight up in power

The big difference between all of the evasive cards you listed and Threatening approach is that it is incredibly unlikely that your opponent will be able to block or by definition, they literally can't block those creatures with the evasive cards. Menace is weaker than either flying or unblockable in most situations in that there are things your opponent can do to block them. As such, I think the +1/+0 makes up in terms of power what the other tricks offer in terms of evasion.
