To improve your strength, create three mono-class squads. Configure Team 1 with your strongest Infantry hero in position 2 and add 100% Infantry troops. Repeat this for Cavalry and Archers.
Once your three best squads are set, check if you have enough troops to create additional mono-class squads. If you have leftover troops, deploy your best available heroes (following the Position 1 rule) and rank them from strongest to weakest. Fill the squad with the troop type of the strongest hero first, then fill remaining slots with the next troop type.
Regarding Blue Heroes: They are useful for gathering but offer no combat benefits. Use them only in Position 3 to fill space. NEVER place them in Position 1 unless gathering.
For optimal combinations and Stress Testing(?), Stress testing involves simulating varied troop/hero combinations to identify the highest power output threshold before combat efficiency drops. use the fan tool: Zienaps Bear Trap Tool
