On the first glance it looks like you'll have big problems with stuff like Knights or Daemon Primarchs.
Not much I can do about that no matter what army I bring to be honest. I doubt I can kill 3 dominus and 2 armigers but most of my army can at least chip away at knights and if they can't then they can take objectives while presenting low threat.
My general experience of the uk meta is that the good players have long ago abandoned Daemon Primarchs so I should be able to outplay anyone still running one if I just play the mission. But even then I'm pretty sure I can kill a daemon primarch and if I run into someone running a daemon primarch and knights then the primarch will be the easier thing to kill.
