Rulings

(4/8/2016)
Geistblast's ability can copy any instant or sorcery spell, not just one with targets.
(4/8/2016)
When Geistblast's ability resolves, it creates a copy of the instant or sorcery spell. The copy is created on the stack, so it's not "cast." Abilities that trigger when a player casts a spell won't trigger. The copy will then resolve like a normal spell, before the original spell resolves but after players get a chance to cast spells and activate abilities.
(4/8/2016)
The copy will have the same targets as the spell it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).
(4/8/2016)
If the spell being copied is modal (that is, it says "Choose one —" or the like), the copy will have the same mode. You can't choose a different one.
(4/8/2016)
If the spell being copied has an X whose value was determined as it was cast (like Avacyn's Judgment's madness cost has), the copy will have the same value of X.
(4/8/2016)
If the spell has damage divided as it was cast (also like Avacyn's Judgment), the division can't be changed (although the targets receiving that damage still can).
(4/8/2016)
If an alternative cost was paid for the spell, such as its madness cost or surge cost, the same alternative cost is considered to have been paid for the copy.
