If Beamsplitter Mage leaves the battlefield or becomes an illegal target for the spell that caused its ability to trigger, that spell is still copied.

If the spell that’s copied has an X whose value was determined as it was cast (like Selective Snare does), the copy has the same value of X.

In some rare cases, the original spell can target another creature but the copy can’t (most likely because an effect modified the characteristics of the original spell on the stack and won’t modify the copy). If the copy can’t target the chosen creature, the copy isn’t created.

The ability triggers whenever you cast an instant or sorcery spell that targets only Beamsplitter Mage and no other object or player, and only if you control another creature that spell could target. If you cast an instant or sorcery spell that has multiple targets and Beamsplitter Mage is chosen as the target in each instance, Beamsplitter Mage’s ability will trigger.

The copy is created on the stack, so it’s not cast. Abilities that trigger when a player casts a spell (like Beamsplitter Mage’s ability itself) won’t trigger.
