Storm (When you cast this spell, copy it for each spell cast before it this turn. You may choose new targets for the copies.)

A Nova is when a white dwarf accretes enough
gas from a companion star to heat it's atmosphere to
the point nuclear fusion happens, caused a violent
explosion. Unlike a supernova, this doesn't destroy
the white dwarf, allowing for this to repeat several
times.
