Everyone knows this, but I recently battled this guy who did this kind of thing, and I lost. I lag too, so maybe this wasn't completely my fault
So he turtled, and when I repeatedly tried harrassing him, he got more castle archers and walls, and then I did 2 giant and 1 magi, with many archers and speartons, while he had 2 magikills, 4 speartons, and some albowtrosses. I attacked with my large army, destroyed some walls and miners, etc, when he attacked with his albows and speartons. I (lagging) placed electric wall on albows and I would have done something else with the speartons had I not lagged, and he revealed his two magikills, placed 2 electric walls, and poisons (he probably didn't lag, nvm) and I left after seeing that I have 2 3/4 health full grown giants who stood there for 20 seconds doing nothing and 1 spearton and 1 archer and my mom coming upstairs.

I probably could've won (maybe?) after that incident by my ok economy and training castle archers myself and others, but I didn't think that would be good.
I DEFINITLY could've won earlier by just continually harrassing him (after destruction of walls) and sending a scout to see those mages who ruined everything, but I was under a timed environment with my mom downstairs, so I decided to get a win and be done with it.

Here are a couple of bullets about my possible win
-scouted with a spearton instead of ghost
-stayed in center and continually harrass his walls and force him to garrison until he brought his army into the open space
-rushed his statue (terrible idea)
-turtled (meh...no...)
-get a better computer

I dunno, but 1. I started with archer sword, saw castle archer, retreated, built some speartons archers, and ghost.
2. rushed base with ghost and 3 archers, killed 1 miner, retreated once he got another castle archer
3. made giants, more spears and bows and 1 mage and all magic,
4. got impatient, attacked with superior army
5. got impatient and laggy computer, clicked a few wrong buttons, and lost with 2 giants remaining with one more castle archer appearing.
6. I still have an ok economy, but not enough to recover from that.
7. Summarily, I need help. Did I do something wrong, or is it just my computer and my mom?

Oh yeah, and I also tried blocking the castle archer arrows with the speartons from my archers, but that didn't work for some reason.

Get 2 shadowrath with shinobi 2 to kill his magikill. Also, pressure him with tower spawn 2 because if you attack him, his 3 CA will come to advantage.

Yes, Magikill are DEFINITELY awesome. They aren't strong soldiers; they're mainly known for their abilities. Their Magikill Wall is amazing; it will damage all units close to the wall quickly. Works best with small health units like Swordwrath and Archidon. Let's say that your opponent gathers 50 Swordwrath; you can destroy them in a matter of few seconds with a SINGLE MAGIKILL. Totally worth it; but doesn't have a good chance of retreat because of its slight sluggishness. Keep it behind the line of your soldiers!
