your graveyard, create a token card called
"Living Flesh" in your graveyard (it is an
X/X black and green living flesh token
creature card with scavenge {b/g} and "the
power and thoughness of living flesh is
equal to the number of living flesh you
control plus the number of living flesh in
your graveyard".)
