Id agree with Ekki on that. but id give it a different spin.
If we can fine tune how different cards effect things like the damage potential curve, etc. we could for example, develop curves for all the false gods. and then, instead of designing a false god deck and then fighting the false god individually to see how effective the deck is against each one. We could just spend a few games getting an idea for that individual deck's curves and then predict which false gods (if any) it would be effective against and have an idea of how effective. without ever playing a single false god with that deck.
You could use that strategy to run through possible deck ideas much faster, and much more efficiently than we do currently. So maybe eventually we could figure out a "best deck" but my end goal here is the tool, not necessarily what people use that tool for later on.
I mean, (talking big picture, not expecting this to happen anytime soon) imagine a deck curve generator, that you could feed your deck code into, and it would tell you which false gods (or common deck types) your deck deck wins against as well as some statistical measure of how often or by how much it would win.
That could drastically change how decks are developed and make the evolution of the metagame occur much much faster.
