It's slightly convoluted, but at absolute worst this is 18 damage for net 2 Energy (assuming you can wait until next turn), and that isn't bad for a Common. Refine Blade's true value shines when you're able to buff the Sovereign Blade further, or play it multiple times, at which point it can start to take over fights. Decent pick-up early, and unlikely to become completely useless even if your run doesn't end up centering on the Blade.
