Glimmervoid Basin — Planechase Planes (OHOP)

Whenever a player casts an instant or sorcery spell with a single target, that player copies that spell for each other spell, permanent, card not on the battlefield, and/or player the spell could target. Each copy targets a different one of them. Whenever chaos ensues, choose target creature. Each player except that creature's controller creates a token that's a copy of that creature.
