I could see this being a common...

Also, red :)

Also an instant? :P

I see the argument for this in white, but it's not really something you'd really want to use lightly... and this card is not worth this harsh bend.

I made this while brainstorming for a private set. The original also had a rider that exiled the creature on death

...which is also, strangely, a red ability.

For what it's worth, though, I disagree with SecretInfiltrator. I don't see how this is so harsh a bend... it seems very slight to me considering that White already has Impeccable Timing and Swift Response.

I think it’s more the player damage
