Norn's Command

As an additional cost to cast Norn's Command, sacrifice X artifact creatures. Each opponent sacrifices X creatures. You gain X life and create
a number of 1/2 white Phyrexian Horror artifact creature tokens with first strike and infect equal
to half the number of creatures that died this
turn, rounded down. Exile Norn's Command.
