hold the perimeter Does this trigger only once on the first upkeep, or is it the first upkeep each turn?
You (and your opponents) only get one "first upkeep". After that, you are past your first upkeep so it will no longer trigger. If it meant the first upkeep each turn, it would use Paradox Haze's template.
