Paying for Spawn-Gang Commander activations with a Worn Powerstone and attempting to use each of the colorless mana from Worn Powerstone for separate activations is an awful and sometimes completely broken experience.

It is pretty easy to reproduce. Attempting to activate with Worn Powerstone in play will cause the auto-tapper to use both colorless mana from the powerstone for a single activation. This auto-tapper behavior is understandable, but not ideal. The real issue is that when entering full control mode, it is incredibly difficult (maybe impossible, in some scenarios) to use the Worn Powerstone colorless mana for two separate activations.

I don't have the time to repeat all the scenarios that I tried to attempt to pay for the ability, but I assure you that I tried everything. Usually, entering full control fixes these types of mana payment issues, but there is some sort of interaction with these two new cards that does not work at all. Incredibly frustrating experience. Please fix.
