Precursor Golem (Schematic) (Serial Numbered) (105) [The Brothers' War Retro Artifacts]

When this creature enters, create two 3/3 colorless Golem artifact creature tokens. Whenever a player casts an instant or sorcery spell that targets only a single Golem, that player copies that spell for each other Golem that spell could target. Each copy targets a different one of those Golems.
