Alright. The middle is crucial for victory. Remember this. But first you need to know how to gain control of the middle. I will tell you this first.
Generally, you should start with 1 Sword and 2 Miners. Put both Miners on gold, and soon you will get your first delivery. Get another SwordWrath. Alright, by now you should have reached the middle. If you see nothing, keep going. RUN AWAY IMMEDIATELY if he has a Castle Archer, and go back to the middle. Not too difficult. Buy more Miners, put 2-3 on mana to get a Spearton.
If you see another SwordWrath:
Wait for your 2nd SwordWrath to load and buy SwordWrath and Archers until you are SURE you can get the middle. Rage will also give you a huge advantage. Don't waste your time on Spearton because Swords with Rage will kill them. Later on, buy Spearton for economy harassment, which I will get to later.
If you see 2 SwordWrath:
Simple. Get more SwordWrath and Archers, same strategy, should be same result. If your opponent is doing the same thing, spamming SwordWrath, get some Ninjas or Magikill to give you an edge. Maybe not Magikill so soon.
Sword/Archer:
This is hard to beat if they're kiting. You should buy a good amount of SwordWrath, enough to survive the kiting, and charge. Since your opponent is behind economically.
Spearton:
This is very simple. You already have 2 SwordWrath by the time your opponent's Spearton loads. He will charge, and you WILL have enough time to buy 2 SwordWrath in the process. You may have to Garrison while your Sword loads. All you need is 4.
The beginning is covered, hopefully.
On to economy harassment. As you are hopefully aware, Swords don't survive Castle Archers. You need Speartons. Either get your own Speartons (or what I like to do is get Tower Spawn and get range units behind them), because they survive. Try to get some Archers BEHIND your unit to help, and the unit will tank the arrows for you. Remember, the more times you get your opponent to Garrison means less gold for him. EVEN if you don't kill any miners.
End game: You should have won by now, at your own level. But if by some miraculous means, your opponent survives, then you will have to proceed. Continue with your Tower Spawn and Archidon behind it. Buy 2-3 Giants as further tanks. By now you should have 1-2 Spearton left over, 1-2 Merics, 7-10 SwordWrath, 10-15 Archidon, and 1-3 Giants(at least grown once). Keep in mind that this will change based on what map you're on. For our purposes, I'm talking about medium sized maps. Your opponent stays at his base. Alright, you need to buy Tower Spawn II, charge behind it and hack away at walls, miners, and statue. Eventually, you'll win.
But if your opponent attacks...
This is assuming your opponent is relatively equal in army strength. Your Swords should take care of Merics and Magikill, maybe the ungrown Giants. Now they should be dead. Position your Giants in front, so they can tank while your Archidon deal damage. You might want to get Allbowtross if you have gotten to this point. A Magikill will also turn the tables quite sufficiently.
Hope this works :)
