Hahahaha! Fantastic flavour :)

That's awesome.

It's like an Un-set variation on Decimate without actually being a ham-fisted pun of a card.

I'm not sure if I've just been misreading this card all along or if this is something you changed, but maybe this should be "target creature you control deals damage..."?

I'm not suggesting that because of power, though this is more or less a Searing Blaze'd Blood Feud, I just think the idea of a "Rage Bomb" and it's presumed affiliation with the Crossblight would mean this is more of a suicide bomber action.

Dan identified a problem with the initial template (target creature you control) during testing; it's a card you want to use to get rid of a big problem, but it effectively costs you two cards to make it happen, and it'll only finish the job some of the time. If you have a 4/4 and I have three 1/1s, the old build was garbage.

This new template helps to make the card much more effective at digging you out of a hole (a position a Crossblight-heavy deck tends to be in with all the sac effects). It also helps to quell some I the early criticisms that the set didn't have much obvious removal, as this is clearly upwards of a 2.5-for-1.

A new name would probably tie the whole picture together better though...
