Players always remain confused about which troops to be upgraded first after construction of laboratory gets completed. The answer is Archers because they are more valuable in longer run if you are very active player who often raids and turns someone else to rubble. These are 3 basic reasons to keep archer in high upgrade priority.
Additionally, archers never pick targets. Unlike the goblins that prioritize the resource building while they attack, the archer can hit any thing on their sight including walls. This gives archers an edge in destroying the base faster as compared to goblins that are picky because resource storages often placed deeper enclosed in the base fully protected.
Lastly, Archers are the excellent troops for Clan Castle, because of their ability to hit from distance that is very dangerous. If they are protected inside the dozens of strong protective walls, you will have an army that can eliminate the enemy without any fear of getting hit back. It is really a deadly combination.
Consider this and the strategy will be more effective if you deploy a complete archer army for a low level Town Hall Base for 1 to 5. In contrast, once you reach the level 6 or above the Town Hall level base, you may want to combine other troops like giants, wall breakers or goblins with archers to have better strategy.
