Can't improvise Rograkh (with commander tax) with Inspiring Statuary


If I'm tap out I can't improvise [[Rograkh, Son of Rohgahh]] that have a commander tax with [[Inspiring Statuary]], I feel that you should be able to because it only needs to pay generic mana and I was unable to find evidence of the contrary.

No files, tests, or entry points are named. Start by reproducing the interaction between Inspiring Statuary, Rograkh, and commander tax while tapped out, then trace the rules handling for improvise and generic mana. Done means the scenario follows the intended Magic rules and has a regression test for the reported interaction.
