Well I've painted round 2, started round 1, preped and primed round 3. I'm now considering what to do for the following rounds, though I do have a unit ready to go for round 5, so round 5 is also primed and ready for paint.
Command figures from Warlord Royalists for round 3.
I'm thinking a unit of Ultramarine Scouts for round 4.
Haradrim Raiders for round 5
Round 6 will have to Pirates
No idea what to do for the other rounds as yet.
