It's tougher than it sounds for a couple of reasons. First, the logistics of getting a bunch of S2 wizards into combat with the enemy pretender is problematic, especially if he isn't a SC.
Second, horror mark will target the highest HP unit in the opposing army. If the pretender is a little guy like an archmage (ripe for horror mark), he'll probably get passed over in favor of that elephant on the back line.
Third, sending in suicide squads of S2 wizards is wasting a lot of S2 wizards. Horror mark x5 is pretty much conceding the battle, and you'll need chaff to buy them the time they need. It gets expensive pretty fast.
