I think fractal devourers might have a chance , but not if he gets a good starting hand.
Removing discord fast is the most important, I would try to counter it with 3-4 deflags. Also cheap shields are the answer since he will probably not use any perma control ( unless he decides to go for But. effect )
But let's think about winning this round first, shall we?
we have emerald shields we could use, but they have high cost
