. Obviously it is likely to fail horribly against Magic, but the Tech can't use their workers for attacking, so they are down to their tower and 3 starting units.
Alternatively, you can mine 120 gold and summon an extra daemon. Depends how fast you think the enemy will build a barracks.
Start summoning daemons and send your 3 acolytes to mine Gold immediately. When the second acolyte drops off his resources (so that you have mined 40 gold so far), promote him to battlemage. Promote each of your other acolytes as soon as they drop off their gold. Once they are finished, attack, even if you're still summoning daemons. Your summoner and the last daemon can tag along later if needed.
If you can, kill any enemies you find along the way rather than fighting them at the same time as you fight the tower. Once at the enemy base, kill any remaining soldiers, then focus on the tower. After that, kill any soldiers the enemy manages to build, and target any workers trying to build a barracks. Destroy any completed barracks (ignore incomplete ones), finish off the remaining workers, and proceed to trash the enemy base.
Continue to produce more and more daemons, sending them to attack as they come, and watch your opponent desperately try to fend them off. If he's spent to much time teching and what-not, you should get an easy win.
3. Turtling and TechingUsed against CPU (ultra), Magic, on One On One.
It took me a while to beat this set-up, mainly because in most games the enemy's initial attacks did too much damage and my economy was too shattered to recover. The key is to know when the enemy is about to attack, and have as many battlemages as possible ready for him. One huge advantage of Magic is that you can train some powerful units (battlemages) quickly and fairly cheaply for defence, as long as you don't mind losing some of your workforce. Compare this to the Tech, who's workers can't even fight.
But as I said, there are probably many other ways to proceed. Overrunning the enemy with scores of magic armor might be one thing to try. I haven't used either them or wicker daemons yet, so there are probably a wealth of untapped strategies involving them.
