This combo came up during a casual game between my friend
and I. I was playing my Leonin/Equipment deck and he was
playing a green spirit deck. Anyways, I had a Leonin den
guard out, and I equipped with a bonesplitter, leonin
scimitars, all that. It was a 18/19 or something like that.
Anyways, this is the good part. I had equipped it with a
Loxodon warhammer last turn, and then I equipped it with
Kusari-gama. My friend had to decide between taking 18
damage or me killing all his creatures (he had 8) and
gaining 18 life for each creature, a total of 144 life. He
conceded after that.
My point here is: If you can get a fatty with a kusari-gama,
your opponent will be stuck between a rock and a hard place.
It's even better if the fatty has loxodon warhammer, or
venom, or... well, you get the idea.
