After what seems to be a recent change, when I use juggernaut 3 on my bonedancer's dread commander, he now gets bigger. However, once juggernaut wears off, he stays the same size. In fact, if I release him and cast a new commander, this new one is still the same size. He only shrinks back down at the moment when I activate juggernaut again so that he's small throughout this second usage of juggernaut. In effect, juggernaut makes my commander big if he's currently small and small if he's currently big, but it never makes him big and then small again once it wears off.
