Welcome to Librarium Online!
Ok so I am kicking around running a Crowe 2500 List for a bit of change on my end. Here it is tear it apart.
Libby w/ 3 powers and 1 servo skull
Purifiers (10 man)
Purifiers (as above)
1 Hammer 1 Psycannon
Razonback w/ TL Lascannon
Grey Knight Terminator Squad
Grey Knight Terminator Squad (as above)
(Heavy Plasma and Multi Melta)
Land Raider w/ Multi Melta x2
The idea is to take the 5 man out of the razorback for Crowe to ride in style. The two 10 man purifiers go in the stormravens with on having the Libby. Shoot across table turn one at flat out to get the purifiers to the fight fastest. Termies will go in the land raiders for control points that won't get pushed off. The five man will go for control point behind Crowe-razor. Simple tactics but effective. My logic being that whatever the purifiers engage in CC will be dead. There is 4 targets for heavy weapons to worry about giving the stormravens a chance to make it to turn 2.
Make sure the librarian takes the shrouding. Cast it turn one when the stom mavens turbo boost and the LRs pop smoke and they all get a 3+ cover save.
