Full Bloodmoon

When Full Bloodmoon enters the battlefield,
It becomes night. Then create blood tokens
equal to the number of non-creature spells in
your graveyard.
{b}{b}: Under the pale moonlight: ({b}{b}, Sacrifice
a creature, it becomes night, & all creatures you
control gain +1/+1 for each blood token you control
until end of turn. Activate only as a scorcery.)
