Well it was hard fought it then end. My dice just hate me. Managed to scrape a win against them. My haywire scourges helped a lot against his sky weavers, but when he realised what I was up to he just disembarked all his troupes and got them into combat quickly. They hit like a truck, and those bikes just mowed down my transports like they were made of paper.
Lelith was amazing though, she managed to kill a solitaire and a shadowseer by herself, and then started on any nearby troupes.
It was a fun game, I should have gone first but he seized. Should I have had the first turn I think I would have crippled him but hindsight is a wonderful thing.
But yeah, following your advice, poison and dissies did the trick. Thanks
