Whenever you sacrifice a creature, create a 2/X
green Phyrexian Spider creature token with reach
where X is equal to the sacrificed creature's
toughness. This ability triggers only once per
turn.
{b/g}, Sacrifice a creature: Until the end of turn, Creatures you control deal combat damage equal
to their toughness rather then their power.
