Wild Ricochet

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).

If the spell Wild Ricochet copies 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.

When Wild Ricochet resolves, it creates a copy of a spell. You control the copy. The controller of the original spell retains control of that 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, after players get a chance to cast spells and activate abilities. The copy resolves before the original spell.
