Ideas and suggestions.

I am absolutely certain that swapping Arcomage and Sacrifice is a positive solution.

I'm not interested in a "positive" solution, but an effective one. To resolve the Arcomage issue.

And I'm somehow sure that a simple swap won't be enough for this. So, "something else" is needed... and that "something else" should be considered before the swap, not after. Perhaps a brilliant idea will come up that will make the swap unnecessary.
