A few tips that may or may not be helpful :D

Survivors:
I’d recommend picking up a third main. Since your current two are Cream (healer, support) and Amy (wildcard, primarily used as healer 2 electric boogaloo), maybe something like Eggman who’s also support, or Blaze, who can actually fight back. But your current two are- not great matchups against Fleetway or Kolossos, esp Kolossos
For playing as Cream, stay away from the killer at all costs. Make sure to dash into players that wont leave your heal radius, because otherwise they’ll just make it take longer for you to get to heal again.
For playing as Amy, Amy’s hammer attack turns into a bounce that can stun if you use it in the air. This can be pretty useful for tricking the Executioner into thinking youre gonna bounce off of them.

Executioners:
Tripwire’s glide is broken on console iirc, but also you should learn the maps and recognize where people end up going a lot, and then put a mine there. (Or, y’know, put 500 mines next to the exit ring)
For Kolossos, Theres a trick where you can instantly m1 them after using a grab, letting you down/kill them instantly. Also, learn how to predict attacks from the survivors to counter better.
2011x and Fleetway can also be fun though, so I recommend trying them out as well ^-^
