As I fight you occasionally in modern I guess you must have similar frustrations to me. The endless bots using Tofu for one. Tofutards I call them. It is here that the Ulund archon shines as you can ignore all the defensive stuff like thorns etc. You can beat a level 1 Tofu about 50% of the time. That's decent considering according to splinterstats you only have about a 19% vhance of winning if you face one in bronze or silver.

One useful Ulund is the one that costs 10 and fires 4 arrow damage. That's coz at level 5 he heals. You have to rent a decent enough Ulund archon to use it though. Generally in bronze and silver you can get away with not using it though.
