Lord of the Unreal

Illusions had always been a tribe with a self-destruct switch: most of them carry a sacrifice clause or fall apart the moment an opponent points removal at them, because the design conceit is that an illusion is a fragile thing that pops when touched. This anthem rewrites both halves of that bargain at once. The +1/+1 turns the tribe's notoriously soft bodies into real threats, and the hexproof grant directly neutralizes the targeted removal and bounce that the illusions' own drawback clauses were built to punish. A Phantasmal Bear or Phantasmal Image that would normally evaporate when targeted simply cannot be targeted by your opponents while this is on the battlefield, which means their sacrifice triggers never fire from enemy removal and the deck stops folding to a single spell. The tension it resolves is that the tribe was designed to be punishable and this card removes the punishment, so the whole archetype lives or dies by whether it stays in play. That makes it the obvious first answer for the opponent and the obvious thing to protect for the pilot, a two-mana 2/2 whose body is almost beside the point. It is the keystone every illusion deck has been organized around since: not a payoff you splash, but the engine that makes a pile of fragile two-power creatures into a coherent, resilient aggressive plan.
