Thoughtbound Primoc

A 2/3 flier whose loyalty is pegged to a board state nobody holds for free: at the start of its controller's upkeep, if one player commands more Wizards than everyone else, the bird defects to that leader. The crucial wording is "your upkeep," and "your" always means the permanent's current controller, so the moment an opponent steals the Primoc, the trigger relocates to them and fires on their next turn instead. The only way back is to break their strict Wizard majority before that upkeep resolves: kill one of their Wizards or deploy enough of your own to at least tie, and the clause stops finding them as a sole leader. A tie controls nothing, since the trigger demands a player control more Wizards than each other player; the moment the count evens out, the bird simply stays put with whoever holds it. So the body bonds to whoever runs the most arcane handlers and abandons you the instant the race tips, which sits crosswise with an early-era impulse to jam a single creature type as hard as possible. It belongs to a small family of designs that punish you for failing to contest a tribe rather than for committing to one, and the joke is that most decks ignored the clause and ran the flier anyway, because Wizards were rarely the thing across the table. Note the precision: this changes control, not ownership, so the bird stays its original owner's card and snaps home the moment the count swings back.
