Blue Sun's Nadir

({p/b} can be paid with either {b} or {1} and 1 life.)
Choose up to three target permanents. If they are enchantments or planeswalkers and {w}{b} was
spent to cast this spell, and/or if they are artifacts
or nonbasic lands and {r}{g} was spent to cast this spell, destroy them. If at least four blue mana
was spent to cast this spell, create tokens that are copies of those permanents instead.
