Walkthroughs for custom maps.

There's one problem: he often starts casting "Shake" almost from the very first turns. This doesn't give enough time to cast "Sandstorm," and for the Medusas to run out of shots.
I'll try to beat him again now, but this time without Harpies.
I don't know how you managed to win with that tactic, because he also has fire and "Suffocate" spells in reserve, which are a bit of a hindrance. So, he keeps casting "Shake" until he destroys all the towers.
