You don't have to cheat, just make your bases do what you need them to do, get some info on base tweaking to make strong and fast bases, maybe use some lateral movement on your O line with some ITZ or Monroe Dials, maybe ( taking a play from coach Smitty) you could have some bases that run backwards to give an illusion of a play going one way than going another, trust me there is enough stuff you can do without cheating your friends, play fair, play hard, and just be better prepared than your opponent.
