Save transmetal for when your priority is speed. This might be during the start or early stages of an event, when you want to upgrade your episode cards immediately to start farming cubes. Or so you can immediately upgrade the X3 card when you hit 2M points.

When speed isn't a priority then open your medals and level existing cards that aren't strong enough to boost your deck, but you want to MTM in order to complete your Cyberdex.
