From town hall 1, whenever you get the access of your first two troops (i.e. Barbarians and Archers) you used to use them as your only troops. But as you advance in your game, more troops unlocks in every town hall level. It's good to try out new troops as they are relatively stronger than the previous troops. As we know, every town Hall level has some unique attack strategy and troop composition to try, but if we want one or two specific strategy which will work from the beginning to the end of the game, Barch is the one in which we can trust.
