Go sig will shut down bastion rather easily and good against other 2 tanks, deff bait out supports cleanse. Worse case they have Ana you should have a kiriko on your team.

Mercy well ping her and focus her down first or rest is meaningless if she revives or does some epic healing.

Honzo maybe grab a ash she can be rather good against him. Or mirror as that’s always funny.

Every situation will be diff though so adapt and make switches as needed.
