This is not hard to beat. Iv'e had players try this on me but it didn't work...... Early scouting is the key. If you see that your opponent is rushing to town phase, then attack well before they can build a civic centre..... If you happen to be late on scouting and you notice that your opponent is in town phase very early, then scout for there civic centre and attack before it is built - civic centres take along time to build and if your opponent has invested all those resources in rushing to town phase and is building a civic centre then there not going to have much of an army to defend.
