This strategy uses speartons a defense for your magikill while you can still use speartons offensively.
1. To start off you are going to want to buy 3 miners with your starting money. You are going to want to keep buying miners until you have 9 (7 mining, 2 praying). If your opponent is rushing you right at the start cancel all of your miners you are buying and get a castle archer. Once your castle archer is out you can continue buying miners.
2. After you have all of the miners you need (and defense) you can start getting your speartons. While you are getting speartons you will also want to be buying electric wall and poison spray for magikill. After your first spearton you want to send him to scout and possibly capture middle tower. If you cant capture the middle tower you will want to wait until you have 2 speartons. If you cant capture mid tower with 2 speartons than wait until 4. If they have an albowtross or two at mid tower than get a magikill early. If you cannot capture middle tower for whatever reason than just try to focus more on defense because they are most likely going to buy ghost tower.
3. Once you have 14-16 speartons you can do either:
A. Get a few merics as well as magikill
B. Get more magikill but no or less merics
C. Get more spearton but less magikill
Or anything else that will help you in battle. What you want to do really depends on what army your opponent has.
Tip: You might want to go into battle a little bit slow because of the pace of magikill and (if you have them) Merics.
