He teamed up his new knight, Gerantius, with his Blood Angels.
I have mostly Iron Knights (Imperial Fist successors), and some Eldar, which I am expanding.
We played Big Guns Never Tire with diagonal deployment. I have Thunderhammer terminators up front and a rhino with a full tac squad behind. Castling up in the corner, I have a lascannon dev squad on the hill with a bunch of sneaky eldar hiding behind it. They are joined by a master of the forge on a bike with a conversion beamer. I have a bike squad with grav and multi melta attack bike next. My cloak and sniper scouts infiltrated and scout moved into the ruin. I have a Crimson Death (3 plane Eldar formation) in reserve.
Luther deployed the mighty Gerantius front and centre. Supporting fire would be supplied by a Deredeo stood high in the ruin.
