Come and Get it!
could depend heavily on the map...What are Doomsdays options at the beginning of the fight? What should I do to increase my chances to get the first hit?
If your playing maps that have interachables within reach from the beginning like Arkham Asylum or Themyscira either jump up and throw the tv/lions or do a venom tackle in hopes of hitting your opponent as they try to jump up themselves.
then it depends n the character, do they have plasma they're gonna chuck at you?
just try your best to get a feel for your opponent options and which ones he or she will be likely to go for and do your best to counter it, and if something goes wrong make a note of it.
