Haha, Kokusho, so original, but a deck based around him, i thought it was rock or tooth and nail, but this seems fun, let's try this out. (in Cali, i've seen lots of people use T/N in their rock deck). (they ue tooth and nail twice and the game's over.)
you've got mana accelaration for Kokusho,
but the only control you have is hand control,
and your creatrues are to much to cast, but all the same this deck is creative and it might work.
the thing with mono black is if your going to run mono black, you definately need Cranial Extraction, and there isn't enough board control for mono-black, unless you sacrifice more than what your suppose to.
but M.B.C. is quite popular, M.B.C w/ Kokusho might be a new one.
