Corrupt Scales

This one has proven quite popular elsewhere.

Corrupt Scales 3
Artifact
Whnever a creature comes into play, destroy each other creature with the same total power and toughness as that creature.

That could be dangerous, it kind of reminds me of Pernacious Deed a bit.

its no where near deed ... it only hits creatures and is not nearly as controlable. its still quite an amuseing card.

like it more as a 3/3 for 3 artifact creature ... thus its own effect can kill it something i like in casual since it opens up some amuesing situations.

ok your could turn it into a 4/4 for 3 now that could actualy be a realy good beater ... one that turnes frogmight into removal for ohh som many problematic creature

[Chodie]

I guess your right on that.

Making it a creature could be interesting, but I think I prefer it as a noncreature.

[Chodie]

How about something like...

{X}{X}
Artifact Creature
When ~ enters the battlefield, put X charge counters on it. Destroy creatures whos total power and toughness are X.

{1}: ~ power and toughness are anything that add up to the number of charge counters. Toughness can't be 0 or less.

[Arix]

That's an entirely different and too much more complicated card.

[Chodie]

I know, but it would still be cool. And i forgot to add that you could only use the second ability as a sorcery.
