Skaven Blitzers provide access to the much needed strength skills, granting a little bit of muscle to compliment the speed Skaven are recognised for.
Gutter Runners are the fastest players in the game and often targeted for fouls. Here are suggested builds and uses for them.
Skaven Linemen are cheap fast and fragile. You need them to take all the hits, though they have some other uses as well.
Skaven Rat Ogres give the team some strength and a bit more resilience. They are quite expensive considering your team is generally fairly cheap.
Skaven Throwers, while less agile than their high agility team mates, can be more effective deep passers. Adding to the already explosive offence.
