Hey Guys,
I thought this would be a fun little card to shake things up a bit. I first wanted to call it Detrivore for decomposing but it was already taken...
Carnivore of the Grave

Creature -- Zombie Insect
*/*
Flash
When ~this~ comes into play, destroy target creature that has already been dealt damage this turn.
~this~ power and toughness is equal to the destroyed creatures power and toughness divided in half to rounded up.
Just to get this right, if your opponent had a 3/3 on the table you'd need to damage but not kill it then you play this for BB, killing the creature and getting a 2/2. Is that right?
I think you meant your text to read "power and toughness divided in half
and rounded up."
