A good thing you told me to tone the guy up. I was fearing that if I added all those things it might come around as unbeatable, but after testing it, I think it´s more balanced than I thought. Maybe still leaning on weak.
To put it into situation, I put him in a late age Ulm game. (This was a matter of practicality, as since I would need to beef up national magicians to get summons going, I´d need lots of gems, and the cheapest "gem" around are blood slaves).
I had him build up a l0-l5 cavalry force, which in battle he would lead from a side of the map down onto the enemy commanders. Heavy infantry would stay at the middle of the map, around an Ulm Commander using a skull talisman over and over, and behind them would be the crossbowmen. This combat set performed amazingly well against independents, as the heavy infantry usually cut through the lesser troops, down to the commanders, and induced mass routs, with little casualties.
Later, I beefed up all formations, throwing in more heavy infantry, more cavalry to the pretender´s cavalry force, and some more archers divisions, plus a wizard (a black priest with Earth l). It's perfomance wasn´t exactly overwhelming, but it kept some big enemy armies from bypassing my frontiers. Plus, I *did* achieve some significative victories against... Vanheim, I think (through I stopped short of their capital). And for some reason, Arcocesphale had it´s Cyclops pretender lovemaking around in a border province, with one some poxy militias as bodyguard, and got killed.
However, that´s when the good times ended. While I was performing cyclopicide, the not-çuite done in Vanheimians came down at me, slaughtered some blood harvesters, and besieged my capital, all in call cutting through two 30+ defense provinces, which usually prove enough to keep back raiding parties (BTW: at this time I had already beefed up a gypsy sorceress to blood 3 death 3, which allowed me to summon my first vampire lord.). My army was able to defeat the besiegers... with losses. I rebeefed him up, so that he had a bigger army, again. I also threw in that vampire count with a bunch of blood slaves so that he could cast imps at the enemy. While I was doing this, Man had invaded the west, and had a not-huge-but-not-disregardable army. In the following engagement, I won, but suffered staggering losses (as in, only five knights survived, about one third of the heavy infantry, and NONE of the archers. Plus a black priest and a good archer hero got killed. I have re-refitted the army again (drawing on the troops which were going to go to the second army, which I need to take care of the Eastern Front). Battling it up without summons is more challenging than it seemed at first, cavalry far less overwhelming than I thought, and building up decent wizards for summons is costly (not that much with blood magic, but it still reçuires several hunters, and to get the blood magic levels which the good stuff reçuires you still need to economize your slaves)
