Try to convince players to attack each other. Bring attention to players that deploy more than you, have more troops than you or have more regions than you. This can bring heat off of you and onto them.
Make an alliance with a player to work against other players.
Encourage stronger players to take out the weakest players since they are the strongest.
These could all be possibilities. This is the problem with no spoils standard games is that if people know how to play most realize that it doesn't make sense to attack a lot. Games like this are usually won by the players that can be the calmest and not let their emotions make them mad while avoiding making other players mad. People usually eventually will get pissed off and suicide into others thus giving the game away. That or everyone sits around holds hands and just keeps deploying every round.
