In Soul Master, one of the most difficult to regain a foothold in the game with. You have to be extra careful not to get ambushed because that would be disastrous. Even teleport would not be life saver because you are cornered. But enough of don'ts. Secure a suitable area (favorably on high ground) with good view on surrounding area and build a base with many buildings. A good way to win the game is to stall it out, at some time the opponent will have to make a move, if they don't, do the same tatic as the bearcat, except just send like 3 tittas.

A good way to stall is build a few turrets at every tractor you have and keep your souls there. Priests alone must play defensive. Making an attack without backup will only result in failure. Secure more tractors then your opponent and wait. The other soul linker will run of seed before you do and launch a desperate attack. Well then for them, it is a game over because of your defense buff and home ground advantage you will destroy all of their souls and leave them wide open. Now you attack. This will not technically be viewed as offensive however, but more defensive as you will guarantee no more attacks, for example, winning the game. Also, you can buy soul master gold to help you fighting in this game.

A way that works really well is the before mentioned ambush or surround. It simply requires you to surround the target area with souls and turrets and wait for the priest to come. Then you rush in, attack, call all units. The priest will teleport, be attacked by souls, teleport again and be attacked by turrets. Then you just follow. Also it is a good idea to set up a gate tower just out of range from their base and summon souls when they retreat. You can then either defeat the priest or eliminate the base.
