The question: Can you use Metabolic Overdrive on a unit that used Hive Commander.
The rules:
Hive Commander: In each of your Shooting phases, you can pick one friendly <HIVE FLEET> unit within 6" of the Swarmlord. That unit can move (and Advance, if you wish) as if it were the Movement phase instead of shooting.
Metabolic Overdrive:
"Use this Stratagem in the Movement Phase, after moving a Tyranids unit from your army."
The precedence:
Opportunistic Advance:
"Use this Stratagem in the Movement Phase when you roll the dice for an Advancing KRAKEN unit."
