I'll second what nurglez said about the executioner and stalkers as follow up purchases when you can (wallet/purse alotting). They give you a good mix of melee/ranged options in lists.

The austringer is a damn near auto include in just about any guild list but definately with ortega's due to the prevelance of companion (24" on use companion chain plus a great cheap model to use to finish off weakened models/ go after totems that give too much capability to your opponents crews).

I myself have gone on record many times in the past as not liking and feeling nino is overated. I would recomend once you get additional models to not including him into lists. To get the most out of him he requires alot of support and against fast mobile crews with damage capability he is a waste of points due to dying first (and trust me he will die first) .

I like running the executioner instead of nino due to dita having obey actually making him usuable ( I mainly find him to slow in other guild led crews but obey allows him to have a threat range to get him in melee and start swinging away), he is a great melee hitter (4,5,7 if triggering crit strike potentially 5,6,8 since he is paired) and like nino he brings a card resource advantage due to his decapitate trigger.
