In those 5 hours Doom travels back in time, learns of the other's prep and finds a way to counter it before returning to the present and making it with reed and bats.
Team two wins this. With Reed and Doom an Batman?? Batman alone in one night is all the prep he needs five months is going overbored. Doom with prep can nearly take down the Avengers. Reed with preep.......... well he's the smartest man I'm sure he will think of Something.
I compare this to that Tiger which had gotten its meal stolen by the Crocs and waited a whom ping 9 hours before they left and a few more for it to come out out the water and it killed it.
As you can see that Tiger had planned for nine hours. The Croc had a few seconds to think of something to do. This is real an can be found on youtube.
