Grand Astudan

Whenever a creature dies, its controller
distributes a number of +1/+1 counters equal to
its power among any number of target creatures
they control.
{3}{w}{b}, Sacrifice Grand Astudan: Each player
exiles all creatures they control and puts X 1/1
white Spirit creature tokens onto the battlefield,
where X is equal to the total power among
creatures they exiled this way.
