My 2000 point, comp-friendly, HtH-heavy, themed army
This list has regularily gotten beaten by all kinds of lists. But I did win 3 games in a row to win Overall in a little Club tourney so it can work. With 2 stubborn units together with the rerolls of the BSB, you'll have a hard hitting centre. This army is HtH heavy so take the fight to the enemy. Use the detachments as meat shields against heavy shooty armies.

Some others......
 
 
 

Empire versus Khemri
This list is untested as of now but will soon see action. It is for my Company of Wolves.
You will notice that I have geared it to be against fear causing creatures and have added some DoW to use those figs which haven't seen a fight in awhile.
 

Empire versus Dwarfs
This list is another Company of Wolves list. You will notice that there is a lot of attacks geared to equal dwarf's T4. Higher S attacks means their usually high armour save will be lessened too. The hero on Pegasus is for anti-warmachine duty. Use terrain to protect him from missiles tho!

Magic heavy Empire list
This list is a generic one but with my own figs in mind. It is really magic heavy and is designed to sit back in a defensive position and hammer the enemy.
Change the Lores to your preference if necessary.
The Hammer of Judgement is an experiment and should be traded if fighting a high Ld enemy.
The knights should be used as a reserve to fill holes in your battle line.

Semi-Unbreakable Empire list (kinda cheesy)
This list shouldn't run! Light the enemy up as they advance and then pounce on the weakened units when they arrive on your line. Keep the main HtH units near the BSB for the rerolls.
