Best: Focus on the Command Building, Barracks, and Military Research. Ignore decorations and overproduction at the beginning. This will speed up the unlocking of your strongest troops before others. 2) Use a "feint attack" before the real one: Launch a small attack with a weak army. Observe whether the opponent uses their shield or withdraws their army. Then immediately attack with your main army. This is a tactic used by professionals to expose the opponent's defenses. 3) Activate speed-ups only during events. Don't waste them randomly. Use them during development or training events to earn points and bonus rewards for the same speed-up.
