There are two ways of generating your strategies firstly by choosing yourself, this can be either where you and your opponent decide between you or in things like Tournaments you may get specific Strategies per round, I often choose specific strategies if I need some practice in a particular one I haven’t played often before a Tournament. The other way is you flip for it; pages 68-70 and 120-121 in the Rules Manual have the tables for for the strategies, you just flip a card from your deck and choose that, you have two tables Core and Expanded to choose from, if you flip the same as your opponent you play a shared strategy, which tend to be very similar to the individual ones except obviously you get vp’s for denying your opponent.
This is the final strategy, like escape and survive model count is key, but also damage potential as in this strategy you need to have more models in your opponents half of the table then they have in yours for 2vp. You get an additional 2vp if you get model(s)into the opposing deployment zone. Summoners like Nicodem and McMourning can really good on the model count front.
That’s the rundown of what you’ll be trying to achieve with your Crew. More soon.
