Ideally, as much as they make now. Again, dynamic income is changing one of the methods of generating income. It does not add a new method to make grinding easier. I have no clue where you're even trying to go with...whatever you're trying to say.
They make 10 per win now. A 200HP deck that wins with 50HP 5 times would win 10 10 10 10 10.
You could make 10 the mark for 100HP, so 200HP decks that win with 50HP 5 times would win 5 5 5 5 5. This would be an example of Dynamic Income being less profitable than the status quo.
You could make 20 the mark for 100HP, so 200HP decks that win with 50HP 5 times would win 10 10 10 10 10. This would be an example of Dynamic Income being the same as the status quo.
You could make 40 the mark for 100HP, so 200HP decks that win with 50HP 5 times would win 20 20 20 20 20. This would be an example of Dynamic Income being more profitable than the status quo.
These are all examples of Dynamic Income, and the profit varies (compared to the status quo) between these examples. Therefore, the implementation of the concept of "Dynamic Income" has no necessary relationship with getting money quicker.
