How to play against heal heavy comps?

I just had a match with a Rem, Kelvin, McGinnis, and Victor and despite everyone in the team buying 2-3 antiheal items it just didn't make any difference. The Victor just afk farmed to like 40k souls and then proceeded to shit on the entire lobby with a medical wing behind him.

I'm just unsure what the strategy should be to respond to that because I've consistently had games where Victor has crazy healing and antiheal just doesn't seem effective. That on top of the new map having endless souls makes him quite hard to play against, so if anyone has any advice please let me know.
